edit /etc/amavis/conf.d/50-user

Comment out the following two lines:

Code:

@bypass_virus_checks_maps = (
   \%bypass_virus_checks, \@bypass_virus_checks_acl, \$bypass_virus_checks_re);

Looks like this:

Code:

#@bypass_virus_checks_maps = (
#   \%bypass_virus_checks, \@bypass_virus_checks_acl, \$bypass_virus_checks_re);

@bypass_spam_checks_maps = (
   \%bypass_spam_checks, \@bypass_spam_checks_acl, \$bypass_spam_checks_re);

Restart amavis:

/etc/init.d/amavis restart
