I have setup Postfix+LDAP+Courier-IMAP+Squirrelmail to support virtual users
PCQLinux 2004 (Fedora core 1)
Postfix installed from source code - postfix-2.0.19.tar.gz Courier-IMAP - courier-imap-3.0.2-1.1 Squirrelmail - squirrelmail-1.4.2-1 rpm installation OpenLDAP - openldap-2.1.22-8 Jamm - jamm-0.9.6 procmail-3.22-11 ( I want to use maildrop instead for filtering and quota capabilities )
I have successfully configured Mail Server for virtual users and its working nice, now i want to do some improvements to existing setup like :
Quarantine - System-blocked mail should be filtered into a mail folder called "Suspicious" that can be reviewed by a user. The messages should be deleted automatically after few days.
Collaborative filtering (share heuristic rules/blacklists with other mail servers, something on the lines of Blade.)
How is Vipuls Razor?
If i use Spamassassin i think it is possible to mark suspicious email as *******SUSPECTED SPAM********** in the subject line and can move that mail to spam folder.
I want to know is there any free anti-virus available to use with Postfix. For this to work properly i think maildrop needs to be configured to filter mails, i am looking for guidelines to do it.
Thanks in advance.
