后缀虚拟域地址不工作

Question

我安装了一个运行Ubuntu20.04LTS和postfix的VPS。使用真实的主机名和后缀发送电子邮件非常有效，但从外部（比如gmail）接收到虚拟地址的邮件是行不通的。

真实主机名邮箱（[e-mail]）从外部接收电子邮件。

将服务器内部的邮件发送到虚拟地址也可以。

echo "test message" | mailx -s 'test subject' [e-mail]

从gmail发送电子邮件会出现“中继访问”错误。

Mail Delivery Subsystem: <[e-mail]>
Subject: Delivery Status notification (Failure)
554 5.7.1 <[e-mail]>: Relay access denied

服务器主机名

domain.name.net

mx记录

dig mailserver.com mx

这个问题现在已经解决了。我们在VPS提供商端没有任何MX记录。添加正确的ip域记录后，一切正常。
