hi, I do follow the http://www.postfix.org/STANDARD_CONFIGURATION_README.html#null_client , i google and said if mail for example.com loops back to myself, then should add myhostname to mydestination, or relay_domains, cause mydestination must be empty so i add to relay_domains.
myhostname = smtp2.example.com mydomain = example.com myorigin = example.com Jul 11 01:43:54 smtp2 postfix/pickup[10975]: 907722BE8003: uid=0 from=<root> Jul 11 01:43:54 smtp2 postfix/cleanup[10991]: 907722BE8003: message-id=<20100710174354.907722be8...@smtp2.ytlcomms.com> Jul 11 01:43:54 smtp2 postfix/qmgr[10976]: 907722BE8003: from=<r...@example.com>, size=1951, nrcpt=1 (queue active) Jul 11 01:43:54 smtp2 postfix/smtp[10993]: 907722BE8003: to=<r...@smtp2.example.com>, orig_to=<root>, relay=none, delay=0.02, delays=0.01/0.01/0/0, dsn=5.4.6, status=bounced (mail for smtp2.ytlcomms.com loops back to myself) virtual entry : root r...@smtp2.example.com postmaster postmas...@smtp2.example.com try sent to root or postmaster have the loops back to myself error message.
