Dear folks,

OpenBSD's spamd is a network level spam filter and consequently we
need the MX records to point to spamd
before it hits our mail server thereby achieving bandwidth protection
as well as spam protection.

This is really fantastic.

Now the issue is this.

Since MX records do not understand TCP port numbers, we cannot have
different MX records point to different
 SMTP servers on the same IP address.

The reason this is a problem is that assume that I have to run
spamd(8) against 100 domains. Do I need to have
100 different IP addresses in my cloud?

I hope the question makes sense. Sorry for sounding confusing.

-Girish
