I am completely aware of it. Most of the connection attempts we are
observing are requests to our mail services trying to relay mail.
Port scans are logged and traced down if possible. Not suprisingly is
that most scans are performed by zombies or even an army of zombies
running some probably hacked Windows. This situation got worse of the
years and there are no indications of an improvement in the future.

BTW: we have set up some honeypots in the DMZ just out of curiosity.
It's extremely interesting to whatch how various attacks are taken

I actually hoped to read an answer from the OP providing some details
to give practical advice if desired.
