amavisd-new
For the first initial setup you may want to use our amavisconf utility.
From amavisd-new-2.5.2-1 we no longer use a random uid/gid, but dedicated ones. Because of this amavis service will not start if you have it installed before, so you have to correct this by issuing these commands:
groupmod -g 40 amavis usermod -u 40 -g 40 amavis chown -R amavis:amavis /var/lib/amavis chown -R amavis:amavis /var/lock/amavis
You should chown any other amavis-owned stuff you may have lying around, these are only the default ones.
