Here's another way to do it. We're testing this right now. I setup amavis-new as a filter for postfix. Then configured amavis-new to use clamav (http://clamav.elektrapro.com/) and spamassassin. Then I end up with headers like this (after some config tweaking): ____SNIP____ X-Virus-Scanned: by amavisd-new X-Amavis-Alert: INFECTED, message contains virus: Eicar-Test-Signature ____SNIP____ or ____SNIP____ X-Spam-Status: Yes, hits=12.1 tagged_above=0.0 required=6.9 tests=CLICK_BELOW, CONGRATULATIONS, EXCUSE_12, EXCUSE_4, FOR_FREE, NORMAL_HTTP_TO_IP, NO_REAL_NAME, REMOVE_IN_QUOTES, REMOVE_SUBJ, SPAM_PHRASE_08_13, SUBJ_FREE_CAP, TO_BE_REMOVED_REPLY, UNDISC_RECIPS X-Spam-Level: ************ X-Spam-Flag: YES ____SNIP____ Then we create a Spam and Virus folders for each user, and give them these for default sieve filters: ____SNIP____ require ["fileinto","reject","vacation","imapflags","relational","comparator-i;ascii-numeric","regex"]; if header :contains "X-Spam-Flag" "YES" { fileinto "Spam"; stop; } if header :contains "X-Amavis-Alert" "INFECTED" { fileinto "Virus"; stop; } ____SNIP____ The customer can then access the messages via squirrelmail. We're having our in house php geek write a cheesy 2-3 option sieve interface that will probably use the php library that avelsieve uses. We're planning on moving the content filtering to a couple of machines in front of our MTA(s) to help distribute the CPU load. Hope that helps. :) Suggestions/Comments? Cheers, Mike
