Mail Relay destination server with non-default port

Hi,

I needed to configure a mail relay for one of our customers. Our customer is hosting his e-mail server at home (don't ask me why ;)) His ISP blocks incoming connections on port 25. So his mailserver accepts mail on a different port (port 21).

So i filled in his IP and port number like this: xxx.xxx.xxx.xxx:21 The transport map generated by virtualmin generates the following entry: domain.tld smtp:[ xxx.xxx.xxx.xxx:21]

Postfix doesn't accept this format, it should be: smtp:xxx.xxx.xxx.xxx:21 (or smtp:[xxx.xxx.xxx.xxx]:21 if you want to disable te MX lookup)
