我使用的是 ubuntu 10.04 的 vps 服务器，当我向 Gmail 发送电子邮件时一切正常，但是对于 Hotmail 却失败了，我检查我的日志发现了这一点：
Mar 19 18:09:01 mail postfix/smtp[6340]: 8FAF722294: to=<[email protected]>, orig_to=<root>, relay=none, delay=0.09, delays=0.08/0.01/0/0, dsn=5.4.6, status=bounced (mail for mydomain.com loops back to myself)
我查看了信息论坛以寻找解决方案，但徒劳无功，甚至我更改了 Postfix 设置：
我的目的地设置是这样的
mail.mydomain.com, localhost.mydomain.com, , localhost
我把它改成了这个
$mail.mydomain.com, localhost, localhost.mydomain.com, mydomain.com
我做了很多改动但仍然不起作用。
输出cat /etc/mailname
mail.mydomain.com
输出postconf -n：
