Answering my own thread again. the answer was no,.. changing my origin didn't make any difference. the messages always get sent to my relays which have no local delivery except postmas...@relay.example.com. The local aliases file works, but the global ( domain ) does not re-write the address it just see's postmas...@example.com, see there is no transport so it sends back to MX, hence my loop. I have read that using virtual alias map may solve the problem. Because the alias does not have to be local. I have always avoided using these because i only have one domain, and figured there was no need to setup a virtual. I guess thi sonly applies if Im using one box and everything is in the box. assuming I need to setup a virtual alias map to accept postmaster@domain which machine should host the database , or should they all have the same database ? any assistance would be helpful thanks. -j
