从我们的 CentOS 6.4 Media Temple DV 服务器向某些地址发送电子邮件时出现退回问题。
我不是专家，但检查邮件日志后发现，邮件被退回是因为收件人服务器无法识别发件人的域。
said: 550 <[email protected]>: Sender address rejected: Domain not found (in reply to MAIL FROM command)
但我不明白为什么 mt-toltech.co.uk 会出现在日志中，因为我们将服务器的主机名和主域更改为 toltechdigital.co.uk
以下内容也出现在日志中
toltechdigital postfix/smtp[3443]: 370A5E38EE: to=<[email protected]>,
我想这就是我想要弄清楚的，这个字段设置在哪里。

我对配置 Postfix 的经验有限，所以我认为我的配置有问题，但我仍然不明白旧主机名的提及来自哪里。
有什么想法吗？
答案1
看起来您已myorigin直接在配置文件中设置了该参数。但是，您可能需要检查该/etc/mailname文件以查看是否仍存在旧主机名的任何残留。也许 Postfix 的某些部分仍在使用它。
另外，您是否使用该命令重建了别名数据库newaliases？
