[rhelv6-list] invalid sender domain - postfix configuration question

[Götz Reinicke]

Hi,

we do have a primary sendmail (rh el 5.x) server and some other new rh
el 6.x servres which use that sendmail system as relay.

I'm new to postfix and did not find the solution for the problem, that
it seam that the mails send from the postfix systems are still nos some
sort of masked by the mail.filmakademie.de sender address.

For all mail originating from the postfix servers (relaied by teh
sendmail server) the receiving servers complain about 'Deferred: 421
invalid sender domain' ... (misconfigured dns?)

Can someone point me to the right config option?

	Thanks and best regards . Götz
