Well, it was not just one thing, but of all the tweaks I had to do,
only one turned out to be cruicial:
I had to comment out one line in

cd /etc/mail


DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA')dnl

i.e. add dnl to the start of the line, and that comments it out:

dnl DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA')dnl

The minor changes are the common sense things that most mail admins know:



You obtain one of these for free from

Uncomment the line

FEATURE(masquerade_envelope)dnl  (i.e. remove the leading # sign and 
leading dnl)

Uncomment the line




service sendmail restart

There are other files that need administration, but that is out of the 
scope of this.
