Abstract

Disclosed is a mail filtering information saving method, comprising: a mail server performing a filtering operation based on a preset anti-spam rule after receiving a mail sent by a user, and generating anti-spam filtering result information, the mail comprising a header and a body; and the mail server generating a current "X-Coremail-Antispam" field in accordance with the anti-spam filtering result information, and adding the current "X-Coremail-Antispam" field to the header of the mail. By implementing the present invention, a mail system administrator can clearly know mail filtering information through the "X-Coremail-Antispam" field. Thus, when the mail is filtered as spam by mistake, the mail system administrator can rapidly know the mail is filtered according to what rules. Meanwhile, the filtering information is uniformly added to the "X-Coremail-Antispam" field, thereby preventing too much cumbersome filtering information from existing in the mail, and facilitating extraction and use. In addition, the information in the "X-Coremail-Antispam" field can be used for intelligent learning to increase the anti-spam effect.

Description

说 明 书 一种邮件过滤信息保存方法、 邮件服务器及电子邮件系统 技术领域  Description A mail filtering information saving method, mail server and email system
本发明涉及通信领域， 特别涉及一种邮件过滤信息保存方法、 邮 件服务器及电子邮件系统。 背景技术  The present invention relates to the field of communications, and in particular, to a mail filtering information saving method, a mail server, and an email system. Background technique
随着互联网技术的迅速发展，电子邮件已经逐渐取代纸件信件成 为人们常用的沟通手段， 电子邮件的普及也造成了垃圾邮件的泛滥， 而邮件系统在过滤垃圾邮件时又经常出现误过滤，及将正常邮件作为 垃圾邮件进行处理， 而用户并不清楚邮件是因何种原因被过滤， 现有 的邮件系统处理垃圾邮件信息时有以下方式及相应的不足：  With the rapid development of Internet technology, e-mail has gradually replaced paper letters as a common means of communication. The popularity of e-mail has also caused the spread of spam, and the mail system often misfilters when filtering spam. The normal mail is processed as spam, and the user is not sure why the mail is filtered. The existing mail system handles the spam information in the following ways and corresponding deficiencies:
有些邮件系统会在邮件信头加上邮件唯一标识的字段，这样可以 通过邮件唯一标识从日志或数据库中查找出反垃圾过滤结果。 但是， 获取反垃圾过滤结果的方法不够方便直接，另外日志或数据库数据可 能因为过期而被删掉， 这样就无法分析原因， 只能重新投递一次再看 结果。  Some mail systems add a uniquely identified field to the message header, so that the anti-spam results can be found from the log or database by uniquely identifying the message. However, the method of obtaining the anti-spam filtering result is not convenient enough. In addition, the log or database data may be deleted due to expiration, so that the reason cannot be analyzed, and the result can only be re-delivered once and then the result.
有些邮件系统会在信头添加一部分反垃圾过滤结果， 如 spf ( Sender Policy Framework ) 结果。 但是， 反垃圾过滤结果的信息会 有很多， 若每一条信息单独作为一个字段， 则信头的字段数会太多，  Some mail systems add some anti-spam filtering results to the header, such as spf (Sender Policy Framework) results. However, there will be a lot of information about the anti-spam filtering results. If each piece of information is used as a single field, the number of fields in the header will be too large.
