I spoke to some very helpful folks on the MailScanner list (especially
Drew) and they sorted me out. I thought I would share in case others
run into this problem. First, MailScanner apparently occurs AFTER the
postfix virtual mapping takes place... so you have to use the
/etc/postfix/aliases vs /etc/postfix/virtual_alias.
Next problem: I had to get /etc/postfix/aliases working together with
the /etc/postfix/virtual_alias table. After banging my head on the
wall for about a day, the answer was embarrassingly simple. You can't
have the same domain in the main.cf variable 'mydestination =' (sends
domains in this list to /etc/postfix/aliases) and
'virtual_alias_domains =' (sends these domains to the
/etc/postfix/virtual_alias table). So, I did this to create a "fake"
subdomain of sample1.com:
/etc/MailScanner/MailScanner.conf
Spam Actions = store forward spam@xxxxxxxxxxxxxxxxxxxxx
High Scoring Spam Actions = store forward spam@xxxxxxxxxxxxxxxxxxxxx
/etc/postfix/main.cf
myhostname = svr.sample1.com
mydomain = sample1.com
mydestination = $myhostname, localhost.$mydomain
virtual_alias_domains = sample1.com, sample2.org
/etc/postfix/virtual_alias
joe@xxxxxxxxxxx joeb@localhost
joe@xxxxxxxxxxx joeb@localhost
bob@xxxxxxxxxxx bob@localhost
@sample2.org frank@localhost
group1@xxxxxxxxxxx joeb@localhost, bob@localhost, bob@localhost
...
/etc/postfix/alias
# Deliver spam to local 'spam' shell account
spam@xxxxxxxxxxxxxxxxxxxxx: spam
The trick was using spam@xxxxxxxxxxxxxxxxxxxxx in both
MailScanner.conf AND /etc/postfix/alias (along with having this
subdomain of sample1.com listed in mydestination of postfix). These 3
items together allowed local delivery without the virtual_alias stuff
getting in the way. MailScanner was now happy and the spam forward
worked.
Let me know if folks see a better way of doing this.
