Right, so for the mail side of life, I need to establish additional MX records
within my DNS that is physically provided by the second server, I take it the
priority should be set to the highest for the main mail server and low for the
backup/second mail server. Thus, if I have the exact same mail.domain.co.uk on
each of the 2 servers, and subsequent vsite and users, then the users of the
domain would not know a single thing about it should the primary go down.

What I do not understand from just doing this. How does the second backup server
automatically que the emails for forwarding onto the primary mail server, once
it comes back online, i.e. say the backup email server had emails awaiting
collection by the users, but the main server came back online before they
downloaded it. How would it be sent on automatically once the primary came back
online.

Cheers for the ideas on the mail side of life.
