Hi Barry,

First, an answer to your question:

If I read your email correctly, you are looking for the
bypass_spam_checks_acl and bypass_virus_checks_acl parameters.

The HOWTO is at http://www.ijs.si/software/amavisd/README.lookups

Perhaps something such as this would do the trick:

@bypass_spam_checks_acl qw(
   1.2.3.0/24
   127.0.0.0/8
   10.0.0.0/8
   172.16.0.0/12
   192.168.0.0/16 );
@bypass_virus_checks_acl qw(
   1.2.3.0/24
   127.0.0.0/8
   10.0.0.0/8
   172.16.0.0/12
   192.168.0.0/16 );

where "1.2.3.0/24" is replaced with the IP range for your network.



A tip: the email above is hard to read and the formating is a bit
random. I had to re-read it several times. I have found that I get
quicker, more accurate responses when I take a few extra minutes to ask
clear, easy to read questions.

The easier you make it for people to help, the more likely they are to
help ;-)
