spam filter to strict?

[Henning]

Hi,

you have to setup amavis correctly in /etc/amavis/conf.d/40-kolab.

The setting you have to adjust is
$sa_tag_level_deflt  = undef;
so that all mail will get X-Spam headers added.

Attached, I share my config, which needs a shared/Spam at domain.com folder
setup and redirects Spam to this folder and to the Spam-Folder in the
user's inbox (if not present, it will get directly to the user's inbox).

Of course you have to setup spamassassins local.cf and I recommend to
setup pyzor, razor and maybe dcc additionally and add them to spamassassin.

Check out
http://laclaro.wordpress.com/2014/02/22/fighting-spam-with-amavis/ there
I pretty much covered everything in more detail. You find the article
also in the kolab planet, but with less color and stuff :)

regards,
Henning
