How can I solve "MX list for hostname points back to hostname" and "config error: mail loops back to myself" messages?
I'm getting these error messages:
553 MX list for domain.net points back to relay.domain.net 554 <user@domain.net>... Local configuration error
How can I solve this problem?
You have asked mail to a domain (e.g., domain.net) to be forwarded to a specific host (in this case, relay.domain.net) by using an MX record, but the relay machine doesn't recognize itself as domain.net. Add domain.net to /etc/mail/local-host-names (if you are using FEATURE(`use_cw_file')) or add "Cw domain.net" to your configuration file.
There are a couple of additional cases where you don't actually want local delivery, and thus adding domain.net to class w is not the right fix:
* When relay.domain.net should just be acting as a forwarder, e.g. a firewall/gateway box. The proper fix could be to set up a mailertable entry for domain.net.
* When relay.domain.net is a secondary (etc.) MX, and the MX mistakenly points to a CNAME or other "non-canonical" name . The proper fix is to point the MX at the actual name, a "work-around" to add the MX target to class w.
Important: When making changes to your configuration file, be sure you kill and restart the sendmail daemon (for any change in the configuration, not just this one):
kill -HUP `head -1 /var/run/sendmail.pid`
Note: You can also get this error message (MX loops ...) when two sendmail systems talk to each other, and both have the same value of $j . The best solution is "don't do that."
mailertable怎麼使用
怎麼 point the MX at the actual name, a "work-around" to add the MX target to class w.

應該是設置有問題，沒有過sendmail,你看下這個文章吧，或許能幫到你，

是用sendmail-cf格式化后的配置
還是直接手工修改的配置
還你是后一種
《解決方案》
config error: mail loops back to me (MX problem?)
dsn=5.3.5, stat=Local configuration error
return to sender: Local configuration error
由上面這些都看出是配置文件有問題
另外DNS 的MX記錄配置正確嗎？

發信本來要發出去的，結果發給自己了。

問題已解決
謝謝各位的回復
問題原因是hostname
將/etc/sysconfig/network中的hostname改為localhost.localdomain
使用hostname命令更改hostname為郵箱所用域名
重啟sendmai
hostname默認配置在rhel5的和fedora10有點不太一樣
再次謝謝各位的回復
