Hey there

I have a mail server running at the moment, set up with iRedMail. It's been working perfectly well for a few months, but my users do get an awful lot of spam. Apparently SpamAssassin wasn't configured or running. This is what I did so far to try and make it work:

1. Edited /etc/default/spamassassin: changed ENABLED to 1. (Otherwise SpamAssassin wouldn't start)

2. Edited /etc/amavis/conf.d/05-domain_id. Added the local domains so it would trigger tags, as such:
   @local_domains_acl = ( [".$mydomain", ".maildomain.com", ".maildomain2.com", ".maildomain3.com" ] );

3. Edited /etc/amavis/conf.d/20-debian_defaults so it would add spam tags to every mail for testing purposes:
   $sa_tag_level_deflt = -1000;

4. Restarted both Amavis and SpamAssassin, to no avail.

Here is the mail.log that shows up when I restart Amavis. It does seem to load the SpamAssassin module.

This is the only Amavis log entry that I get when I received a mail:
