be sure to block any and all
ports for smtp, 25, 465, 587, 2525 (not a comprehensive list of ports) for
both incoming and outgoing connections.
Please read the SMTP RFCs. 25 is for unauthenticated mail and if that is
allowed, it can be used as a spambot.
465 and 587 are for authenticated mail. If the user does not have
credentials on the remote server, it cannot send mail.
2525 is not standardized at all for mail.
Exclude port 25 in the ExitPolicy, not only the firewall. Otherwise your
relay might end as a Bad one.
