[Mimedefang] mimedefang and trend micro's interscan viruswall

[Stephen Loeckle]

Well, I don't have trophie or any other interface to trend installed.
Here's what I've done. I setup Interscan and Sendmail just the way Trend
suggests in the sandwich config. This is the setup where you have a
sendmail daemon on port 25, then trend on 18000 and finally sendmail on
19000. Email path:

Old:
Internet -> sendmail on port 25 (does dnsbl) -> trend on port 18000 ->
sendmail on port 19000 -> recipient

New:
Internet -> sendmail on port 25 (does dnsbl) -> trend on port 18000 ->
sendmail on port 19000 (mimedefang) -> recipient

When I found Spamassassin and Mimedefang, I recompiled sendmail to use
Milters. The daemon on port 25 doesn't have a milter in it's cf file.
However the daemon on 19000 does have one for mimedefang. Attached are my
mc files tweaked for trend so I don't have to do the funky cf
modifications. This setup works great for me. I get around 8000 emails on
an average day on this box which is a dual proc p3-1.2ghz box. Proc util
is max at 20%.

If this doesn't make sense, let me know. I have a tendency to ramble and
lose people.

P.S. Pay no attention to the LDAP stuff at the bottom. We're migrating
back-end servers...
