I would suggest using an invalid TLD of .local to prevent any chance
of collision with a "real" domain (davmor2-local.co.uk could be
registered!).  My suggestion would be to use davmor2.local as the
private domain name.

While it is not essential, it is good practive to have a reverse zone
as this will speed up anything that tries to do a IP to name lookup.
This also can be used as an anti-spam measure by refusing email from
any IP that does not have a reverse lookup zone.

This should be on the davmor2.co.uk (public) domain, not your private

Once you are happy that the DNS server is setup right, change
/etc/resolve.conf to use  If you cannot then resolve
external names (eg "host www.google.co.uk" gives an error) check that
you have configured the DNS server to use a forwarder (or 2) eg use
the IP address of your router.  Alternatively, browse to your router
status page and find out the IPP addresses of your ISP's DNS servers
and use these as the forwarders.
