I'd still like to hear from anyone running a SMTP server on Linux, not NOS.
Not exactly understanding what you are trying to solve here.
ISPs may block SMTP traffic on IP addresses that they have little or no
control over as they don't want to end up on some RBL someplace (eg
SpamHaus). In that case they would only open port 25 traffic up to an
MX that they control. That MX may have various spam filtering on it and
they would have a way to log traffic to track down "abusers".
