The complete output generated by the  '# postconf -n' command is appended

Besides that, I have not configured postfix in any particular way...
As previously indicated, Mailman works well with any external Email address,
but not with the ones co-hosted on the same physical server...

Any idea about what the problem could be ?

Ignore the above portion of my prior reply. I wasn't paying enough attention
to what the actual issue was.
