Is there any way to prevent a firewall running smapd (port 25) from
acting as a mail relay for mail that neither came from, nor is going to,
your domain?  Our mailer is sendmail 8.8.8, and I've put into my the anti-relay measures suggested on several websites
( being one).  If I kill smap & just run sendmail as a
daemon, they work great.  However, if I run smapd as the primary
listener, the rules fail & the mail gets relayed.  Thanks!
