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
