With professional anti-virus software it seems they listen on Port 25 (the
ones i have checked) and only seem to be able to send to one SMTP
server. I am not really sure what other arrangement you mean. I had
header/body content matching on the first server just as a way of
reducing what gets to the second postfix server, which will be doing
more intensive work, such as checking for viruses in attachments, etc.

Of course, this is all based on my non-existent statistics on performance
issues...
