Please refer to Figure 1, an email sending method provided by the embodiment of the present application, the method includes:

S101: The sender obtains the original email;

S102: The sending end adds first extended information to the original email, so as to obtain the processed original email;

S103: The sending end sends the processed original email to a receiving end, so that the receiving end can control the operation authority of the original email based on the first extended information.

It should be noted that, in the specific implementation process, the above-mentioned mail sending method provided by the present application can be applied to mail clients using any protocol to send and receive mail, such as: IMAP (Internet Mail Access Protocol, Interactive Mail Access Protocol), POP3 (Post Office Protocol 3, the third version of the Post Office Protocol), SMTP (SimpleMail Transfer Protocol, Simple Mail Transfer Protocol), ESMTP (Extended SMTP, extended SMTP) and other protocols. And the mail client can build various mail servers to use, just complete the configuration according to the relevant mail server address, for example, if a mail client wants to use SINA mail server, you can configure the receiving mail server address (POP3) It is: pop.sina.com.cn or: pop3.sina.com.cn, and the sending mail server address (SMTP) is: smtp.sina.com.cn, and it can be used. This method is widely used and easy to operate.

Below, in conjunction with Figure 1, the specific implementation steps of the email sending method will be introduced in detail:

Step S101, the sender obtains the original email. The email format of the original email here is not limited. It is MIMO, an email technical specification widely used at present. The full name is "MultipurposeInternetMailExtensions". The more accurate Chinese name is "Multipurpose Internet Mail Extensions". The mail body is composed of two parts. The mail header contains important information such as sender, recipient, subject, time, MIME version, type of mail content, etc. The main format and content are as follows (of course, the following formats are just examples It can be in other formats, which are not limited in the embodiment of the present invention):

Date:Tue,31Jan 2012 10:07:39+0800

Content-Type: multipart/related;

boundary="----=_001_NextPart076188650547_=----"

The mail content of the original mail may include text, image, sound, and various attachment formats.

In step S102, the sending end adds first extended information to the original email, so as to obtain the processed original email.

Among them, in the embodiment of the present application, the first extended information is used to control the operating authority of the receiving end to forward and/or reply to the original email, for example: the first extended information controls the receiving end to prohibit forwarding and replying to the original email, Prohibition of forwarding and prohibition of replies and so on. It should be noted that the first extended information can also be used to limit the receiving end's daily operation rights visible to the mail client, such as archiving and printing the received mail, which is not limited in the present invention.

As an optional embodiment, if the first extended information contains the first preset content, the operation authority of the receiving end on the original email is prohibition of forwarding; and/or, if the first If the extended information includes the second preset content, the operation authority of the receiving end on the original email is prohibition of replying.

Wherein, the first extended information may include a variety of extended information, such as: the first function field, the first function flag, etc., and the first preset content (or the second preset content) is also different based on the difference of the first extended information, The content of the first preset content (or the second preset content) will be introduced later. After receiving the processed original email, the receiving end can determine whether the original email contains the first extended information, and if it contains the first extended information, it can control the operation authority of the original email based on the first extended information.

As an optional embodiment, the sender adds the first extended information to the original email, and the specific steps include: the sender embeds the first function field in the original email; the sender assigns a value to the first function field, wherein the first The value assigned to the function field is different, and the operation authority of the receiving end on the original mail will be different.

Specifically, if the assignment of the first function field is the first preset value, the operation authority of the receiving end to the original mail is prohibition of forwarding; and/or, if the assignment of the first function field is the second preset value, then the recipient The operating authority of the terminal to the original email is prohibition of reply.

Specifically in this embodiment, an example is given: the first functional field embedded in the original mail is XX-CanNotXX, if the value of XX-CanNotXX is 0 (certainly also other values, such as: 00, 10, etc.), Then the operating authority of the receiving end to the original mail is to prohibit forwarding, and the receiving end does not provide the operating authority of forwarding the original mail. At this time, the first preset content in the first extended information is the first preset content assigned to the first function field. Set the value (for example: 0, 00, 10, etc.); if the value of XX-CanNotXX is 1 (of course, it can also be other values, such as: 01, 11, etc.), the operation authority of the receiving end to the original mail is Replying is prohibited, so that the receiving end does not provide the operation functions of replying and replying to the original mail. At this time, the first preset content in the first extended information is the second preset value (for example: 1, 01, 11, etc.); if the value of XX-CanNotXX is 0/1 (of course, it can also be other values, such as: 00/01, 10/11, etc.), the operation authority of the receiving end on the original mail is prohibit reply and Forbid forwarding, so that the receiving end does not provide the operation functions of forwarding, replying, and replying all for the original mail; The operating authority of the original email mentioned above is, for example, prohibiting forwarding and only replying to the sender, then the receiving end will not bring the text of the original email when replying. At this time, the receiving end does not provide the operation functions of forwarding and replying all, but provides reply operation function.

As another optional embodiment, the sending end adds the first extended information to the original mail, and the specific steps include: the sending end adds the first function mark to the original mail, based on whether there is the first extended information in the original mail received by the receiving end Function mark, the operation authority of the receiving end to the original mail is different.

Specifically in this embodiment, an example is given to illustrate: the sending end adds the first function mark to the original mail, and the first function mark is, for example, XX-CanNotFW, XX-CanNotRE (certainly also can be other function marks) etc., and then the receiving end is in After receiving the mail, it can be judged whether the mail contains the first function flag, and then the operation authority on the original mail can be determined.

Further, according to whether there is a specific first function flag in the original email, the operation right of the receiving end to the original email is controlled to prohibit forwarding, and/or prohibit reply.

Specifically in this embodiment, an example is given to illustrate that different first function fields can be set for the forwarding authority and the replying authority. The operating authority of the original email is to prohibit forwarding, and the receiving end does not provide the operating function of forwarding; if the first function mark added by the sending end to the original email is: XX-CanNotRE, the operating authority of the receiving end on the original email is prohibiting reply, so that the receiving end The end does not provide the operation functions of reply and reply all; if the first function tag added by the sender to the original email is: XX-CanNotRE&FW, the operation authority of the receiver to the original email is prohibit reply and forward forward, and the receiver has no control over the original email The operation authority of the email is prohibit reply and prohibit forwarding, so the receiving end does not provide the operation functions of forwarding, replying and replying all. Of course, the above correspondence between the first function field and the operation authority is only an example, not a limitation. In the above solution, the first preset content (or the second preset content) is the first function field.

In the above solution, only the first function field needs to be assigned to the original mail, and the receiving end can control the operation authority of the original mail without multiple operations, thereby reducing the processing burden of the sending end.

Further, if the operation authority of the receiving end on the original email is prohibition of forwarding, the first prompt message for prompting prohibition of forwarding is given at the receiving end; and/or,

If the operation authority of the receiving end on the original mail is prohibition of replying, then a second prompt message for prompting prohibition of replying is given at the receiving end.

Specifically in this embodiment, an example is given: the first prompt information (or the second prompt information) is, for example, text, picture, sound, etc., after the receiving end can determine that the operating authority of the receiving end to the original mail is prohibition of forwarding, Add the first prompt information (or the second prompt information) directly in the original mail, and then the receiving end directly reads the first prompt information (or the second prompt information) in the processed original mail and outputs the first prompt information ( or the second prompt message); or, the receiving end only adds the corresponding first extended information to the original mail, and if the receiving end, after receiving the processed original mail, parses out that the operation authority for the original mail is prohibition of forwarding, then Generate the first prompt message and output it; if it is analyzed that the operation authority for the original email is forbidden to reply, then generate the second prompt message and output it, and so on.

The receiving end can output the first prompt information (or the second prompt information) in the form of a pop-up prompt window, or display it in the form of a watermark in the text of the received email, and the specific display method is not specifically limited in the present invention.

In the above solution, the receiving end can generate prompt information (the first prompt information or the second prompt information) for the corresponding operation authority, so the user at the receiving end can be prevented from generating useless operations, so as to improve the efficiency of mail operations.

As another optional embodiment, the sending end adds the first extended information to the original email, so as to obtain the processed original email, which specifically includes:

The sender packages the original email as an attachment of a new email;

The sending end adds the first extended information to the new mail, so as to obtain the processed original mail.

Wherein, the attachment can be an attachment in any format, such as: a compressed file, an email, etc. As an optional embodiment, in order to further improve the security level of the original email, the attachment is generated by encrypting and packaging email, so that the original email can only be analyzed and obtained when the receiving end knows the password of the attachment.

Specifically, in this embodiment, an example is used to illustrate: the packaged attachment is in the format of data.360smail, which includes a file header description and real file content.

File header description:

1st Byte: version number;

2nd, 3Byte: encrypted data verification value;

4-99Byte: temporarily empty.

The real file content:

After 100Byte: the data file of the real encrypted email.

For example, a symmetric encryption algorithm can be used to encrypt the data file content EML of the mail, and the encryption strength is AES256.

As an optional embodiment, if the mail receiving system of the receiving end is a designated mail system, the receiving end can obtain the original mail contained in the attachment; if the mail receiving system of the receiving end is not the designated mail system system, the receiving end cannot obtain the original email contained in the attachment.

For example, the inability to obtain the original email included in the attachment includes: the receiving end cannot download the attachment, the receiving end can download the attachment but cannot parse the original email, and so on. The specified mail system can be the same mail system as the mail receiving system of the sender, or any mail system selected by the sender. For example, the mail system of the sender is 360 mail system, and 360 mail system sets a special code for decoding mail by itself. Format, after the sending end processes the original email into this special format, it will be sent to the receiving end as an attachment of a new email; after receiving the processed original email, if the receiving end determines that its mail receiving system is not the 360 mail system, then Control that the receiving end cannot download attachments; or, the receiving end can read the original email in a special format. If the receiving end is also a 360 mail system, it can parse the original mail. If the receiving end is not a 360 mail system, the receiving end Unable to parse the original message.

In the above solution, only the specified mail system can obtain the attachment contained in the original mail, so the security of the original mail propagation is further improved.

As an optional embodiment, if the receiving end is not the designated mail system, the receiving end provides third prompt information after obtaining the processed original mail, and the third prompt information is used for Instruct the receiving end to use the designated mail system.

Specifically in this embodiment, an example is used to illustrate: the third prompt information can be text, image, audio, etc., wherein, if the third prompt information is text or image, then the third prompt information will pop up a prompt on the client receiving the mail window, or display the body of the received email in the form of a watermark, etc., for example: if the sender sets only the 360 mail system to be able to parse the original email, after the receiving end obtains the processed original email, if the current email receiving system sends If it is not the 360 mail system, the following third prompt message "Please use the 360 mail system to parse the attachment" can be generated through a pop-up window. Of course, the present invention does not specifically limit the specific display method of the third prompt message.

Further, in step S102, the processed original email further includes: second extended information, and the second extended information is used to control the expiration time of the original email.

Specifically, in this embodiment, an example is used to illustrate that the second extended information can be added to areas such as the mail header and the mail body of the original mail.

Through the above solution, the expiration time of the mail can be effectively controlled, thereby further improving the security of mail transmission.

As an optional embodiment, the second extended information is a second function field, and if the value of the second function field includes a time point, the original email becomes invalid after the time point; if the first If the value of the second function field does not include the time point, the original email will not be invalidated. For example, in a specific embodiment, the second function field is XX-LoseEfficacy, and the set value is: Tue, 10Feb 2015 15:36:57+0800, which means that the expiration time of the original mail is February 10, 2015 15 :36:57, if the current email viewing time has exceeded the expiration time of February 10, 2015 15:36:57, the original email will be invalid and cannot be browsed normally. Otherwise, if the value of the second function field is empty, it means that the original email is not subject to expiration time control, and the original email can be browsed indefinitely.

As another optional embodiment, the second extended information is a second function mark. If the original mail obtained by the receiving end contains the second function mark, the original mail will be sent after a preset time period. Invalidation; if the original email obtained by the receiving end does not contain the second function mark, the original email will not be invalidated. Wherein, the preset time period can be manually set by the user when sending an email, or can be automatically set and generated by the system. For example, the system is set to expire after 2 months from the email sending time. The specific preset time here The implementation form is not limited. For example, in a specific embodiment, if the second function is marked as XX-LoseEfficacy in the original email, and the expiration time set by the system is one month after the sending time, and the sending time is 10 o'clock on January 1, 2016 1 point, then 10:01 on February 1, 2016 is the expiration time of the original email. If the current reading time has exceeded the expiration time, the original email has expired and can no longer be read.

Through the above solution, the expiration time can be set for emails in batches, thereby improving the efficiency of setting the expiration time.

Next, step S103 is executed, the sending end sends the processed original email to the receiving end, so that the receiving end can control the operation authority of the original email based on the first extended information. Specifically, after the sending end sends the processed original email, that is, the original email with the first extended information added, to the receiving end, the receiving end controls the operating authority of the original email based on the specific conditions of the first extended information, specifically The implementation method will be described in detail in the following content.

Please refer to Fig. 2, according to another aspect of the present invention, also provide a kind of mail control method, comprise:

S201: the receiving end receives the email sent by the sending end;

S202: The receiving end reads the first extended information added by the sending end in the email;

S203: The receiving end controls the operation authority of the email according to the first extended information.

Below, in conjunction with Fig. 2, introduce the specific implementation steps of this mail control method in detail:

Step S201, the receiving end receives the mail sent by the sending end; the mail format of the original mail here is MIMO format, which is composed of two parts: the mail header and the mail body, and the mail header includes the sender, recipient, subject, time, Important information such as MIME version, type of mail content, etc., wherein the mail content of the original mail includes text, image, sound, and various attachment formats, etc.

Then step S202 is executed, the receiving end reads the first extended information added by the sending end in the mail;

Wherein, in the embodiment of the present application, the receiving end reads the first extended information added by the sending end in the mail to control the operating authority of the receiving end to forward and/or reply to the original mail, for example: through the first An extended message controls the receiving end to prohibit forwarding, prohibiting reply, prohibiting forwarding and prohibiting reply, etc. of the original mail. It should be noted that the first extended information can also be used to limit the receiving end's daily operation rights visible to the mail client, such as archiving and printing the received mail, which is not limited in the present invention.

As an optional embodiment, if the first extended information contains the first preset content, the operation authority of the receiving end on the original email is prohibition of forwarding; and/or, if the first If the extended information includes the second preset content, the operation authority of the receiving end on the original email is prohibition of replying.

Wherein, the first extended information may include a variety of extended information, such as: the first function field, the first function flag, etc., and the first preset content (or the second preset content) is also different based on the difference of the first extended information, The content of the first preset content (or the second preset content) will be introduced later. After receiving the processed original email, the receiving end can determine whether the original email contains the first extended information, and if it contains the first extended information, it can control the operation authority of the original email based on the first extended information.

As an optional embodiment, the receiving end reads that the sending end adds the first extended information to the original mail as the first function field embedded in the original mail by the sending end; the first function field is assigned by the sending end, wherein , the value assigned to the first function field is different, and the operation authority of the receiving end on the original mail will be different.

Specifically, if the assignment of the first function field is the first preset value, the operation authority of the receiving end to the original mail is prohibition of forwarding; and/or, if the assignment of the first function field is the second preset value, then the recipient The operating authority of the terminal to the original email is prohibition of reply.

Specifically in this embodiment, an example is given: the first functional field embedded in the original mail is XX-CanNotXX, if the value of XX-CanNotXX is 0 (certainly also other values, such as: 00, 10, etc.), Then the operating authority of the receiving end to the original mail is to prohibit forwarding, and the receiving end does not provide the operating authority of forwarding the original mail. At this time, the first preset content in the first extended information is the first preset content assigned to the first function field. Set the value (for example: 0, 00, 10, etc.); if the value of XX-CanNotXX is 1 (of course, it can also be other values, such as: 01, 11, etc.), the operation authority of the receiving end to the original mail is Replying is prohibited, so that the receiving end does not provide the operation functions of replying and replying to the original mail. At this time, the first preset content in the first extended information is the second preset value (for example: 1, 01, 11, etc.); if the value of XX-CanNotXX is 0/1 (of course, it can also be other values, such as: 00/01, 10/11, etc.), the operation authority of the receiving end on the original mail is prohibit reply and Forbid forwarding, so that the receiving end does not provide the operation functions of forwarding, replying, and replying all for the original mail; The operating authority of the original email mentioned above is, for example, prohibiting forwarding and only replying to the sender, then the receiving end will not bring the text of the original email when replying. At this time, the receiving end does not provide the operation functions of forwarding and replying all, but provides reply operation function.

As another optional embodiment, the receiving end reads the first extended information added by the sending end to the original mail and adds the first function mark to the original mail by the sending end, based on whether there is a first function mark in the original mail received by the receiving end. A function mark, the receiving end has different operation rights to the original mail.

Specifically in this embodiment, an example is given: the sending end adds the first function mark to the original mail, such as XX-CanNotFW, XX-CanNotRE (of course, other function marks can also be used), etc., and then the receiving end after receiving the mail, It can be judged whether the mail contains the first function mark, and then the operation authority on the original mail can be determined.

Further, according to whether there is a specific first function flag in the original email, the operation right of the receiving end to the original email is controlled to prohibit forwarding, and/or prohibit reply.

Specifically in this embodiment, an example is given to illustrate that different first function fields can be set for the forwarding authority and the replying authority. The operating authority of the original email is to prohibit forwarding, and the receiving end does not provide the operating function of forwarding; if the first function mark added by the sending end to the original email is: XX-CanNotRE, the operating authority of the receiving end on the original email is prohibiting reply, so that the receiving end The end does not provide the operation functions of reply and reply all; if the first function tag added by the sender to the original email is: XX-CanNotRE&FW, the operation authority of the receiver to the original email is prohibit reply and forward forward, and the receiver has no control over the original email The operation authority of the email is prohibit reply and prohibit forwarding, so the receiving end does not provide the operation functions of forwarding, replying and replying all. Of course, the above correspondence between the first function field and the operation authority is only an example, not a limitation. In the above solution, the first preset content (or the second preset content) is the first function field.

In the above solution, only the first function field needs to be assigned to the original mail, and the receiving end can control the operation authority of the original mail without multiple operations, thereby reducing the processing burden of the sending end.

Further, if the operation authority of the receiving end on the original email is prohibition of forwarding, the first prompt message for prompting prohibition of forwarding is given at the receiving end; and/or,

If the operation authority of the receiving end on the original mail is prohibition of replying, then a second prompt message for prompting prohibition of replying is given at the receiving end.

Specifically in this embodiment, an example is given: the first prompt information (or the second prompt information) is, for example, text, picture, sound, etc., after the receiving end can determine that the operating authority of the receiving end to the original mail is prohibition of forwarding, Add the first prompt information (or the second prompt information) directly in the original mail, and then the receiving end directly reads the first prompt information (or the second prompt information) in the processed original mail and outputs the first prompt information ( or the second prompt message); or, the receiving end only adds the corresponding first extended information to the original mail, and if the receiving end, after receiving the processed original mail, parses out that the operation authority for the original mail is prohibition of forwarding, then Generate the first prompt message and output it; if it is analyzed that the operation authority for the original email is forbidden to reply, then generate the second prompt message and output it, and so on.

The receiving end can output the first prompt information (or the second prompt information) in the form of a pop-up prompt window, or display it in the form of a watermark in the text of the received email, and the specific display method is not specifically limited in the present invention.

In the above solution, the receiving end can generate prompt information (the first prompt information or the second prompt information) for the corresponding operation authority, so the user at the receiving end can be prevented from generating useless operations, so as to improve the efficiency of mail operations.

As another optional embodiment, what the receiving end reads is the first extended information that the sending end packs the original email into an attachment of the new email and adds to the new email.

Wherein, the attachment can be an attachment in any format, such as: a compressed file, an email, etc. As an optional embodiment, in order to further improve the security level of the original email, the attachment is generated by encrypting and packaging email, so that the original email can only be analyzed and obtained when the receiving end knows the password of the attachment.

Specifically, in this embodiment, an example is used to illustrate: the packaged attachment is in the format of data.360smail, which includes a file header description and real file content.

File header description:

1st Byte: version number;

2nd, 3Byte: encrypted data verification value;

4-99Byte: temporarily empty.

The real file content:

After 100Byte: the data file of the real encrypted email.

For example, a symmetric encryption algorithm can be used to encrypt the data file content EML of the mail, and the encryption strength is AES256.

As an optional embodiment, if the mail receiving system of the receiving end is a designated mail system, the receiving end can obtain the original mail contained in the attachment; if the mail receiving system of the receiving end is not the designated mail system system, the receiving end cannot obtain the original email contained in the attachment.

For example, the inability to obtain the original email included in the attachment includes: the receiving end cannot download the attachment, the receiving end can download the attachment but cannot parse the original email, and so on. The specified mail system can be the same mail system as the mail receiving system of the sender, or any mail system selected by the sender. For example, the mail system of the sender is 360 mail system, and 360 mail system sets a special code for decoding mail by itself. Format, after the sending end processes the original email into this special format, it will be sent to the receiving end as an attachment of a new email; after receiving the processed original email, if the receiving end determines that its mail receiving system is not the 360 mail system, then Control that the receiving end cannot download attachments; or, the receiving end can read the original email in a special format. If the receiving end is also a 360 mail system, it can parse the original mail. If the receiving end is not a 360 mail system, the receiving end Unable to parse the original message.

In the above solution, only the specified mail system can obtain the attachment contained in the original mail, so the security of the original mail propagation is further improved.

As an optional embodiment, if the receiving end is not the designated mail system, the receiving end provides third prompt information after obtaining the processed original mail, and the third prompt information is used for Instruct the receiving end to use the designated mail system.

Specifically in this embodiment, an example is used to illustrate: the third prompt information can be text, image, audio, etc., wherein, if the third prompt information is text or image, then the third prompt information will pop up a prompt on the client receiving the mail window, or display the body of the received email in the form of a watermark, etc., for example: if the sender sets only the 360 mail system to be able to parse the original email, after the receiving end obtains the processed original email, if the current email receiving system sends If it is not the 360 mail system, the following third prompt message "Please use the 360 mail system to parse the attachment" can be generated through a pop-up window. Of course, the present invention does not specifically limit the specific display method of the third prompt message.

Further, in step S202, the information read by the receiving end from the email also includes second extended information, and the second extended information is used to control the expiration time of the original email.

Specifically, in this embodiment, an example is used to illustrate that the second extended information can be added to areas such as the mail header and the mail body of the original mail.

Through the above solution, the expiration time of the mail can be effectively controlled, thereby further improving the security of mail transmission.

As an optional embodiment, the second extended information is a second function field, and if the value of the second function field includes a time point, the original email becomes invalid after the time point; if the first If the value of the second function field does not include the time point, the original email will not be invalidated. For example, in a specific embodiment, the second function field is XX-LoseEfficacy, and the set value is: Tue, 10Feb 2015 15:36:57+0800, which means that the expiration time of the original mail is February 10, 2015 15 :36:57, if the current email browsing time has exceeded the expiration time of February 10, 2015 15:36:57, the original email will be invalid and cannot be browsed normally. Otherwise, if the value of the second function field is empty, it means that the original email is not subject to expiration time control, and the original email can be browsed indefinitely.

As another optional embodiment, the second extended information is a second function mark. If the original mail obtained by the receiving end contains the second function mark, the original mail will be sent after a preset time period. Invalidation; if the original email obtained by the receiving end does not contain the second function mark, the original email will not be invalidated. Wherein, the preset time period can be manually set by the user when sending an email, or can be automatically set and generated by the system. For example, the system is set to expire after 2 months from the email sending time. The specific preset time here The implementation form is not limited. For example, in a specific embodiment, if the second function is marked as XX-LoseEfficacy in the original email, and the expiration time set by the system is one month after the sending time, and the sending time is 10 o'clock on January 1, 2016 1 point, then 10:01 on February 1, 2016 is the expiration time of the original email. If the current reading time has exceeded the expiration time, the original email has expired and can no longer be read. Through the above solution, the expiration time can be set for emails in batches, thereby improving the efficiency of setting the expiration time.

Next, step S203 is executed, and the receiving end controls the operation authority of the mail according to the first extended information.
