Thanks Phil & Lanwench for your helpful tips. I now have a solid base to
start from. The concept of an 'official mail server' is logical but I would
never have thought of it.

It also seems to mean that when our current ISP closes shop, our domain name
is up for grabs for some time; I assume I can only set up our DNS once the
current ISP has 'released' the name, otherwise there would be 2 DNS servers
serving the same domain. How should I ensure the continuity of our domain
name?
