Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a flowchart illustrating steps of a first embodiment of a mail processing method according to the present invention is shown, where the method is applied to a mail filter, and specifically may include the following steps:
step 101: and when the mail to be processed is received, calling a first idle thread to receive the mail content corresponding to the mail to be processed, and sending the mail content to the strategy matching process.
In the embodiment of the present invention, the mail filter may include four parts, namely, postfix (mail transfer agent), mail filtering process, policy matching process, and management platform, where the mail filtering process may receive mail data sent by postfix through the 10025 port and interact with postfix in the form of SMTP message.
The mail filtering process adopts a single-process multithreading mode, and when the mail filtering process monitors that the port has the mail to be processed sent by postfix, a first idle thread is called to receive the mail content corresponding to the mail to be processed.
The first idle thread is any idle thread selected by the mail filtering process from the thread pool. It should be noted that, when the mail filtering process receives the to-be-processed mail, and there is no idle thread in the current thread pool, the mail filtering process notifies postfix to block waiting, and sends the to-be-processed mail to the mail filtering process after the first preset time.
And after the first idle thread is called, the first idle thread receives the mail content corresponding to the mail to be processed and sends the mail content to the strategy matching process.
It should be noted that, after receiving the mail content corresponding to the mail to be processed, the first idle thread stores the mail content and the information of the receiving and sending person, and generates a unique identifier uuid for the mail, where the uuid and the mail may be 34-bit digital codes. After the uuid is generated, the first idle thread packages the uuid and the postfix connection information to obtain package information, wherein the package information may include the uuid of the mail, socket information for connecting the mail and the postfix, a mail file name and a timestamp.
Optionally, after the first idle thread generates a uuid for the email, setting the state information of the email to incoming, where the incoming indicates that the email is successfully received but has not been sent to the policy matching process. After the first idle thread sets the mail status information to incoming, the mail status information may also be encapsulated in the encapsulation information.
And after the first idle thread obtains the encapsulation information, inserting the encapsulation information into the hashmap. Optionally, the first idle thread may further store the encapsulation information in the database, so that the user may view the encapsulation information of each email stored in the database.
After the first idle thread performs the above processing on the package information of the email, the email content may be sent to the policy matching process.
Optionally, after the first idle thread sends the mail content to the policy matching process, the mail state information of the package information inserted into the hashmap is modified, where the modified mail state information is active, and the state of active indicates that the mail content has been sent to the policy matching process, but the matching result is not obtained.
Optionally, in an embodiment of the present invention, after the step 101, the method may further include:
step A1: the first idle thread is released.
Optionally, after the first idle thread sends the mail content to the policy matching process, the first idle thread is released, so that the first idle thread can be continuously used. It should be noted that, if the state information of the mail is modified by using the first idle thread after the content of the mail is sent to the policy matching process, the first idle thread is released after the state information of the mail is modified to active.
And after the first idle thread is released, the first idle thread is recycled into the thread pool.
Step 102: and matching the mail content according to a preset filtering strategy through a strategy matching process to obtain a matching result.
In the embodiment of the invention, after receiving the mail content sent by the first idle thread in the mail filtering process, the strategy matching process matches the mail content according to the preset filtering strategy to obtain a matching result, wherein the matching result comprises information that the mail content is successfully matched or information that the mail content is unsuccessfully matched and uuid of the mail.
If the matching of the mail content is successful, it indicates that the mail content includes content that should be filtered according to the preset filtering policy, and the mail may have spam, viruses, malicious programs, sensitive content, and the like, and should be blocked. And the matching of the mail content fails, which indicates that the junk information, viruses and the like are not found in the mail, and the mail can be released.
Optionally, the step 102 may include:
substep B1: and receiving a preset filtering strategy issued by a management platform through the strategy matching process.
In the embodiment of the invention, the strategy matching process can receive the preset filtering strategy issued by the management platform. The management platform can receive the preset filtering strategy configured by the user through the web page.
It should be noted that, after receiving the preset filtering policy configured by the user, the management platform sends the preset filtering policy configured by the user to the policy matching process.
Substep B2: and matching the mail content according to a preset filtering strategy, and determining a matching result.
In the embodiment of the invention, the strategy matching process matches the mail content according to the preset filtering strategy sent by the management platform which is received last time, judges whether the mail content hits the preset filtering strategy or not, and determines the matching result according to whether the mail content hits the preset filtering strategy or not.
Step 103: and calling a second idle thread to receive the matching result.
In the embodiment of the invention, the mail filtering process calls the second idle thread to receive the matching result sent by the strategy matching process.
The second idle thread may be a predetermined thread in the mail filtering process, which is dedicated to receive the policy matching result, and the second idle thread may also be the same thread as the first idle thread.
Step 104: and executing corresponding processing on the mail to be processed according to the matching result.
In the embodiment of the invention, when the second idle thread receives the matching result sent by the strategy matching process, the corresponding processing is executed on the mail to be processed according to the matching result.
Specifically, the second idle thread judges whether the hash map has the encapsulation information of the e-mail corresponding to the uuid according to the uuid of the e-mail information included in the matching result, if the corresponding encapsulation information is not found in the hash map, the matching result is considered as invalid data, and the second idle thread continues to wait for receiving the matching result sent by the policy matching process.
If the second idle thread finds the packaging information of the e-mail corresponding to the uuid in the hashmap, the e-mail to be processed needs the second idle thread to execute corresponding processing according to the matching result, wherein the corresponding processing is executed as follows: and judging whether the mail is blocked or released according to the matching result, namely whether the matching is successful or failed, and informing postfix to block the mail or release the mail.
Optionally, after the second idle thread performs corresponding processing on the to-be-processed email, the encapsulation information corresponding to the email in the hashmap is deleted, and the corresponding state information is modified into done, where the state is done to indicate that the email has been matched by the policy matching process, a matching result is obtained, and the postfix is notified to perform processing, and the second idle thread may store the state information of the email in the database, so that the user may obtain the information of the processed email through the database.
Optionally, the step 104 may include:
substep C1: and when the matching result is a result of successful matching, preventing the mail to be processed from being received/sent.
In the embodiment of the invention, when the matching result is successful, the second idle thread sends socket information based on the SMTP to the postfix, the socket information comprises information that the matching result is successful, and after the postfix receives the socket information sent by the second idle thread, the successful matching information in the socket is identified, and the mail to be processed is prevented from being received or sent. Specifically, if the mail to be processed is a mail to be received through postfix, the mail to be processed is prevented from being received, and if the mail to be processed is a mail to be sent through postfix, the mail to be processed is prevented from being sent.
Substep C2: and receiving/sending the mail to be processed when the matching result is the result of failed matching.
In the embodiment of the present invention, when the matching result is a matching failure, the second idle thread sends, to the postfix, socket information based on the SMTP protocol, where the socket information includes information that the matching result is a matching failure, and after the postfix receives the socket information sent by the second idle thread, the postfix identifies the matching failure information included in the socket, and then receives or sends the to-be-processed mail. Specifically, if the mail to be processed is a mail to be received through postfix, the mail to be processed is received, and if the mail to be processed is a mail to be sent through postfix, the mail to be processed is sent.
The mail processing method provided by the invention can improve the working efficiency of the mail filter, reduce the mail accumulation and improve the timeliness of e-mail transmission. In addition, the state information of the mails is continuously updated, the state of the mails can be fully and timely recorded, the statistical analysis of the mails is facilitated, and the experience of users is improved.
Optionally, in an embodiment of the present invention, the method may further include:
step D1: and recording the acquisition time corresponding to the mail content.
In the embodiment of the invention, when the first idle thread receives the mail content sent by the postfix, the acquisition time corresponding to the mail content is recorded, the acquisition time can be recorded in a timestamp mode, and after the first idle thread receives the mail content, information such as uuid of the mail, the timestamp of the mail, socket information connected with the postfix and the like is encapsulated, encapsulated information is obtained, and the encapsulated information is inserted into a hashmap.
Step D2: and calling a third idle thread to acquire the current time.
In this embodiment of the present invention, the third idle thread may be a predetermined thread in the mail filtering process, which is specially used for checking whether the mail to be processed is overtime, and the third idle thread may also be the same thread as the first idle thread.
The third idle thread can acquire the current time in real time, traverse the hashmap, and acquire respective timestamps of the multiple mails from the encapsulation information of the multiple mails inserted in the hashmap, where the time recorded by the timestamps is the acquisition time of the multiple mails.
Step D3: and calling the third idle thread, and calculating the absolute value of the difference between the current time and the acquisition time.
After the third idle thread acquires the current time, the third idle thread may be called, and a difference absolute value between the current time and the acquisition time is calculated, where the difference absolute value is an interval duration from the start of the acquisition of the mail content to the current time.
The third idle thread may calculate an absolute value of a difference between the current time and the acquisition time according to the acquisition time obtained from the timestamp and the current time, and perform step D4.
Step D4: and receiving/sending the mail to be processed under the condition that the absolute value of the difference is greater than the preset time length.
The preset time duration refers to a time duration for acquiring the mail content preset by a service person, and the preset time duration may be 5min, 10min, and the like, and specifically may be determined according to a service requirement, which is not limited in the embodiment of the present invention.
After the absolute value of the difference between the acquisition time of the mail content and the current time is calculated, the magnitude relation between the absolute value of the difference and the preset time length can be used for judging whether the time is out from the acquisition of the mail content.
It should be noted that the third idle thread only notifies postfix to allow the overtime mails, and the mails which are not overtime are still processed according to steps 102 to 104, so as to prevent the mails from being allowed to pass.
Optionally, after the third idle thread notifies postfix to release the overtime mail, the encapsulation information corresponding to the overtime mail is deleted from the hashmap, and the state information corresponding to the overtime mail is modified to timeout-forward, where the state is timeout-forward and indicates that the mail is released overtime, and the third idle thread may store the state information of the mail in the database, so that the user may know the information of the mail that has been released overtime through the database.
The mail processing method provided by the invention can enable the mails which do not receive the matching result for a long time to be released in time, thereby avoiding the situation that the mails are accumulated and the user cannot receive the mails for a long time, and improving the operation efficiency of the system and the satisfaction degree of the user.
Optionally, in an embodiment of the present invention, the method may further include:
step E1: and calling a fourth idle thread to acquire the number of the mails of which the current time state information is incoming.
In the embodiment of the present invention, the mail filtering process calls a fourth idle thread to obtain the number of mails of which the current time status information is incoming, where the fourth idle thread may be a predetermined thread in the mail filtering process, which is specially used for checking whether mails to be processed are stacked.
In the embodiment of the invention, after the first idle thread generates uuid for the mail, the state information of the mail is set as incoming, the state information of the mail is packaged into the packaging information, and the first idle thread also inserts the packaging information into a hashmap and stores the packaging information into a database.
And traversing the hashmap by the fourth idle thread, and acquiring the number of the mails of which the current time state information is incoming from the packaging information inserted by the first idle thread in the hashmap, or acquiring the number of the mails of which the current time state information is incoming from the packaging information stored in the database.
Step E2: and judging whether the number of the mails of which the state information is incoming exceeds a first preset number.
And the fourth idle thread acquires the number of the mails of which the current state information is incoming, compares the number with a preset first preset number, and judges whether the number of the mails of which the state information is incoming exceeds the first preset number. If the number of idle threads exceeds the threshold number, step E3 is executed, and if the number of idle threads does not exceed the threshold number, step E1 is executed after the fourth idle thread sleeps for 1 minute.
Step E3: and if the number of the mails exceeds the preset number, the fourth idle thread informs postfix to release the mails to be processed with the second preset number.
And if the fourth idle thread judges that the number of the mails of which the state information is incomings exceeds the first preset number, informing postfix to release the mails to be processed of the second preset number, and optionally informing postfix to release the mails of which the current state information of the second preset number with the earliest acquisition time is incomings.
After the fourth idle thread executes step E3, the fourth idle thread loops to execute step E1.
The mail processing method provided by the invention can realize that partial mails are released when the mails in the mail filtering process are excessively accumulated, thereby avoiding the situation that the mails cannot be received by a user for a long time due to the accumulation of the mails and improving the operation efficiency of the system and the satisfaction degree of the user.
