每当我发送“root”邮件时，我都希望它被转发到[email protected]（而不是本地发送）。
但是，我一直这样做：
Feb 9 17:41:54 botmaster postfix/smtp[29969]: B6E0B808F5: to=<[email protected]>, relay=none, delay=0.01, delays=0.01/0/0.01/0, dsn=5.4.6, status=bounced (mail for botmaster.corp.flatturtle.com loops back to myself) 这是我的main.cf：

有几种方法来禁用本地交付，但他们似乎没有工作（或至less，我不断得到这个消息）。

“邮件循环回自己”只有一个原因：postfix发送邮件到它负责的收件人域，例如RCPT TO：[email protected]，而$ myhostname是example.org的MX。
没有configuration来解决这个问题，因为它是你configuration的 。
将根的别名添加到不在您的后缀框上的某处，例如：
root: [email protected]
Postfix不允许发送电子邮件到SMTP标题中具有相同myhostname的目标SMTP服务器。 然后，您必须将当前myhostname设置为backup.example.org或其他。
myhostname是机器名称，为了避免这个问题，您可以将MX服务器名称设置为“dexter.example.org”，并将备份服务器名称设置为“deedee.example.org”。 RFC 1178说'使用主题名称'。
我通过在名称服务器上创build一个新域名find了一个解决方法：“botmaster.corp.flatturtle.com”。
MXlogging指向另一个SMTP服务器。
因此，邮件根目录（添加@ botmaster.corp.flatturtle.com域名）被转发并正确传送。
