    Default Spam filter problems

    I've installed OX on Ubuntu 6.10 LTS, everything is working fine except spam filtration. I used martin's installer to get everything going and then I made sure spam & virus filtration is enabled for everyone, I turned on the email scanner too.

    When i turned on the scanner it added the necessary entries to my postfix.conf to send things through procmail for filtration. This caused a bunch of errors on send/receive because I didn't have procmail installed. I installed it and everything seems good except I'm receiving a ton of junk. I see all my incoming mails going through the filtration system:
    Code:
    Received: from mail.xxx.com ([unix socket])
    	 by mail.xxx.com (Cyrus v2.2.12-Debian-2.2.12-4ubuntu1) with LMTPA;

    EDIT!
    And here is my /etc/postfix/master.cf:

    However no filtration information shows up on my headers (scoring etc) and I receiving a ton of viagra adds etc. Are there some setup options that I need to configure to make sure this is working?

    Also, it seems like there were a few times where my procmail executable disappeared from my system, I may just be imagining this though.

    As you can see in the config amavisd is responsible for spamfiltering (it gives the mails to spamassassin).

    So what do you want to do with procmail

    I didn't add procmail, when I enabled mail scanning in the open-xchange admin console it added all those lines. It turns out everything was running correctly but some lines in my amavis configuration were commented out, namely

    Code:
    @bypass_virus_checks_maps = (
       \%bypass_virus_checks, \@bypass_virus_checks_acl, \$bypass_virus_checks_re);
    and

    Code:
    @bypass_spam_checks_maps = (
       \%bypass_spam_checks, \@bypass_spam_checks_acl, \$bypass_spam_checks_re);

    Those lines have to be commented out to have your mail scanned by Amavis.
    If you still encounter the same problems when they are commented out, try to send an eicar.com.txt testfile, to be sure Amavis itself is working fine.
