Since my forte is not  REs, I need some help creating a rule.  Basically,
what I would like to do is "whitelist" ALL local mail.  My idea behind
this is that mail generated by us to our users should NEVER get spam
tagged.  Now I can't really whitelist my domain, as many spammers will use
local e-mail address in the from header.  I could whitelist a few "key"
address, but that would allow some spam to get through via the whitelist,
and there should be a way to have a rule check for local mail instead.

My thought would be to have a regex look at the received headers and if
they only come from local IPs, then it would give them the whitelist
score.  All of our IPs have both A and PTR records in our DNS server, so
it should be easy to determine if the e-mail is "local" meaning that it was
sent from a local IP to our mail server, then delivered.

Thanks,
