I can send out e-mail to
tester@exampledomain.com
exampledomain.com being my real domain the message goes to Postfix server in DMZIP1 which forwards the message to Postfix5. The message however is not delivered locally as expected but instead Postfix5 tries to forward the message back to DMZIP1 and then goes into a loop until multiple hops are exceeded and the message is dropped.
So the server behind DMZIP1 has no problem routing the message to Postfix5 however he receives to deliver it to tester who has a mailbox there configured via Cyrus.
Postfix5 ip in this case is 192.168.0.1 and also the server is able to send out e-mails from outlook client connected to it. The e-mails go out via DMZIP1 without problem.
I did read a book on the subject but still can`t find the solution why the server is not accepting the message for local delivery.
