Hi Alexander,
thanks for your comment. The output from that echo command is empty. And
in my sendmail configuration there are no MASQUERADE* options set at all.
My 'problem' is, if configured our sendmail mail environment some long
time ago and everything worked for our setup. Adding the postfix new
servers made/require some changes.
So my mailserver relaying knowledge got a little bit rusty ...
Basically I use the default configurations provided by redhat.
So may be you could give me some mor advises?
Thanks a log and best regards Götz
