Don't know if I should say this *out loud* - but no firewall   :-o (not
yet)


My exchange admin tells me there is a problem with the relay setup on
the Linux machine.   I have played around with the relay settings, but
no luck.  To be honest, I do not know the syntax of the settings in the
main.cf file, and the documentation isn't helpful in this regard either
(no examples).
