e-mail domain template
Add the ability to automatically create e-mail routing on a second server when a mail domain is made.
We have a separate server which does spam filtering, based on MailScanner/Postfix. Our MX records point to this server, this server contains a transport map in postfix which routes the mail to our hosting server (ISPConfig).
In some cases we've configured an alternate route to Exchange servers of customers, in these cases it's also necessary to add the port number to which the mail gets delivered.
e.g. example.com smtp:[exchange.example.com]:587
