Have you tried the SmartHost setting your SMTP configuration, so that
your email is relayed through your ISP's mail server?

Your mail server might be utilizing a dynamic IP address from your
ISP, which has been blacklisted due the spam zombies with SMTP engines
sending junk from users on DSL, Cable, Dial-up, etc... most of which
are dynamic IP's.
