Been there, done that, way ahead of you.

You may not be aware of this, but while filtering outbound SMTP stops
outgoing spam, it does not stop portscans, or various other activities
which will cause that IP to be blacklisted on various networks, as they
are free and should be free to do. You also may not be aware that
performing frequent network scans and cleanups as we do does not make
you immune to infection from new online threats.

"Whatever" is not a network abuse strategy, I am afraid.

So an ill informed knee jerk reaction from you means that a potential
bug in postfix goes unfixed.

Thanks for your help so far, it is appreciated.
