Mail being dropped undelivered after postfix

[Kolab Users]

Hi Eric,

Wallace is a content filter which is enabled by default in Kolab3 
(together with amavisd). Most of the time they don't cause problems.

You'd want it enabled if you don't have external tools that do the email 
filtering for you. If you do, just disable them.
