Clement 2.6-2.11 发布，电子邮件服务器

Clement 是一个电子邮件服务器。它的主要功能是在电子邮件交流过程中尽快阻止不需要的电子邮件（垃圾邮件）。 It accepts or rejects email while the SMTP session, initiated by the email sender, is still pending, accepting legitimate email messages without the need to return an error status to non-existent or "borrowed" return address later. Clement can operate in two modes. Either the mail is taken into account locally and stored in the recipient's own area, or it can transmit the mail to an another SMTP server (Sendmail, Postfix, Exim, Exchange, etc.). Each email domain name Clement knows about can be treated in one of these two modes depending on the group to which the domain name has been set. Each message is verified by a virus scanner (ClamAV) while the SMTP connection is still open, but the refusal of mail and the reason for refusal is notified to the actual sender. Mail management is done via a Web interface and can be delegated to three administrative levels (Root-Admin, Group-Admin, Domain-Admin). Standard users can access their own logs (sent email status, email rejected, quarantined email, etc.). With this interface, the user can handle the rejection and acceptance of mail. Users who are level "Admin" can access the session logs (via the Web interface). Clement uses a SQL database (PostgreSQL, MySQL) to store and manage logs, user profiles, and dynamic management of directives concerning the sender-receiver relationship.

发布日志: This version's main improvement is the ability to define a user alias a piped process. This can be easily defined via the Web interface (domains manag. -> click user domain -> aliases -> New alias). A pipedemo.sh shell script can be used as a starting point
