Only for relatively simple configurations. My last sendmail.mc (dating
to the time of the Lovebug 'virus' more or less) contained more cf in it
than mc; whilst Sendmail has improved over the years, what I do in an
MTA has increased in complexity 5 fold so I dare say if I were still
doing it in Sendmail, my mc would still contain lots of cf.

Hmm. Odd. It may be worth trying to capture what both Sendmail and
Postfix are trying to send with tcpdump.

You mean like :-

The most obvious problem with running an MTA in a private LAN is that
the MTA needs to be told the fqdn of the wan ip address but I think
you've got that covered.

        It's a bad idea to let third parties generate outbound mail
        traffic from your mail system to destinations of THEIR choice.
