Configuration

Download a sample configuration file and place it in /etc/amavis/amavis.conf amavis.conf

Fill in all your localdomains. This would include any virtual domains you are hosting. Escape all periods with a backslash as in the sample below.

;; Which domains should be considered local? Recipients are notified
;; about mail that was stopped only if they are local. The domain name
;; is matches against this Perl regular expression.
local domain = .*example\.com

Select who should get notification that you've found a virus, I suggest at the minimum you set it to notify admin

;; Who should be notified?
notifiers=Sender, Recipients, Admin

Modify the mail from and admin lines to reflect your local domain.

;; What address will appear in the From:-header of warning messages
mail from = postmaster@<your domain goes here>

;; Who is the mail admin? Comma separated list if multiple admins
admin = postmaster@<your domain goes here>

Mailfront Configuration

Update mailfront to use amavis-ng rather than /var/qmail/bin/qmail-queue

Run the following command
/sbin/e-smith/db configuration setprop smtpfront-qmail filter /usr/sbin/qmail-queue.amavis

If your using my secure mail addon you need to also run the command
/sbin/e-smith/db configuration setprop ssmtpfront-qmail filter /usr/sbin/qmail-queue.amavis

Now reconfigure your mail settings to use the new settings:
/sbin/e-smith/signal-event email-update
