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 didn´t recognize that the email must be routed to the Secondary domain hosting GWIA.
I did a top down rebuild with no success.
Any suggestion ?
