我有个简短的问题。当发送到具有主服务器子域的电子邮件地址时,如何设置后缀以将电子邮件发送到另一个服务器(Exchange )。例如,假设我们的主服务器是mail.example.com,并且我们有一个Exchange设置来接收来自exchange.example.com的电子邮件。我们在DNS中设置了MX记录,如果我们从GMail帐户发送,它将正确接收。但是,当我们试图从@example.com帐户发送电子邮件时,会出现以下错误:
Host or domain name not found. Name service error for name=exchange.example.com ty
