[OT] sendmail priority

[TAC Forums]

The subject is slightly off topic, its Sendmail.

We have a sendmail server, which we would like to configure with Real
time blackhole lists, to reject as much SPAM as possible. Also we have
SMTP Authentication enabled on the same server.

If, a genuine user is on a blacklisted IP address and he uses our SMTP
server, will his mail be rejected?

What gets higher priority, during an incoming SMTP connection, SMTP
authentication or Real time blackhole listing?

Regards,

Boskey
