You can use black and white lists affect on sender address. These lists are plain text files reside in Eserv mail directory. Black lists are named spammers* (spammers.txt, spammers.com.txt etc), white lists are named friends* (friends.txt, friends.hotmail.com.txt etc). They contain e-mail addresses, one address per line. You can use wildcards in spammers*. If sender address not found in friends* and matches any template found in spammers*, the mail message is moved to the mail\loop folder (if it is already downloaded from external POP3 mailbox) or does not accepted (if comes via SMTP).

In order to analize mail content you need some external utility. For example, POPfile — see http://popfile.sourceforge.net/

P.S. Examples of lists: spammers.txt:


friends.txt:
