Therefore, pay attention to the usage of roaming users (roaming users do not include $ mynetworks, for example, users who access the Internet by dialing at another ISP.

However, generally all network interfaces are open to receive emails from any network interface, which sets the inet interfaces parameter value to "all ".Mydestination = $ mydomain, $ myhostnameThe Postfix will receive the email only when the recipient address of the sent Email matches the value of this parameter. For example, here you set this parameter value to $ mydomain, $ myhosname, indicating whether the recipient
