postfix "loops back to myself"
我们客户公司(infor-trans.com)的邮件发不进我们公司邮箱(cn-gd.uc.com.tw)，他们管理员传给我的maillog如下:maillog:
Mar5 10:02:51 mail postfix/smtp: ACB5812A2DF: to=<sales2@cn-gd.uc.com.tw>,relay=127.0.0.1:10025, delay=0.56, delays=0.11/0/0.2/0.25,dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as F378F12A4B9)

Mar5 10:02:52 mail postfix/cleanup: 8B6BB12A81B: message-id=<20070305020252.8B6BB12A81B@localhost>
还不知道清楚如何解决，收集的资料如下说
Linuxforum上的贴子
解决办法:
修改master.cf,10024端口的加一个myhostname = filter.domain.com
myhostname不要和main.cf里边的一样
原因:
$ telnet localhost 25
Trying 127.0.0.1…
Connected to localhost.localdomain (127.0.0.1).
Escape character is ‘^]’.
220 mail.domain.com ESMTP Postfix
~~~~~~~~~~~~~~~~
postfix的远程投递代理smtp在联接到smtp端口后,检查上面波浪线的部分和myhostname是否相同
相同则认为是loop了.
改一下master.cf就可以了噢.
还有一种可能是查出来的primary mx的IP和你机器上的某个IP相同,也会被认为是loop.
最后我在main.cf中mydestination中增加localhost.$mydomain
而客户也发信说把他们的main.cf中myhostname=localhost改成mail.infor-trans.com
就可以正常接收他们的信件了，看来还是hostname的问题

34. I can't seem to receive messages. What does this error mean: ": mail for example.com loops back to myself"?Postfix reports this error when a DNS reply points to your mail server, but Postfix hasn't been configured to deal with messages addressed to the domain. Postfix accepts mail for domains listed in mydestination, relay_domains, virtual_mailbox_domains, virtual_alias_domains, and domains that resolve to IP addresses listed in inet_interfaces and proxy_interfaces.
