OK, thanks for the confirmation.

Brilliant, thanks for the info.

That's a good idea. But then internal e-mails need to go out to the ISP, don't they? Because, if internal e-mails get delivered locally, the vacation 
autoresponses on the ISP will not trigger, will they?

The trouble is, with that configuration, if the Internet link goes down, internal e-mail stops working too.

I was hoping that there would be a complete mail server setup guide somewhere for this kind of setup. But I guess I'll have to piece all these 
information snippets together.
