Creating an external domain ("New External Domain" button)

A domain on an external mail server.

Create such kind of domain only if you want to use e-mail accounts on already existing domain on another mail server. For instance, if you do not use XMail Server at all and only use WebMail Pro web interface to access mail hosted on another server.

If you wish to host the domain on your XMail Server, create an internal domain instead.
