All outgoing Internet mail returns User not on PO error = D101.
GW8 linux system, 1 Primary Domain with 1 PO. 1 Secondary Domain with GWIA. SLES10 sp1, OES 2 sp1.
I didn't see the outgoing mail at GWIA agent log. It seems that the poa refused the email back to the user and didnt recognize that the email must be routed to the Secondary domain hosting GWIA.
I did a top down rebuild with no success.
Any suggestion ?
