:I'm trying to get the hang of this... Can someone explain?
:If I want to receive Internet mail, I might attach a machine
:foo.company.uk to the network, and have this as my mail address
:directly. I'd like, though, to have company.uk as my email address.
:
:Should I:
:   a) call the machine company.uk instead
:   b) have company.uk as an alias for foo.company.uk
:   c) register company.uk as a name with MX records
:        pointing to foo, then foo-backup, foo-reserve etc

I'd do b) and c).  Some mailers, like what Sun and Apollo enable by
default, don't support MX records, so it's usually a good idea for an
alias to be set up.  This is kind of in the spirit of "Be liberal in
what you accept and conservative in what you send out".  So you'd have
a machine named foo.comp.uk.  It'd have an alias to comp.uk.  Then
you'd have MX records for comp.uk pointing to foo.comp.uk,
foo-backup.comp.uk, etc.  

:When a large organisation has a "high-level" email address
:(dec.com, mitre.org, mit.edu  [though these are just guesses])
:do they usually correspond to physical machines, or to virtual
:machines with MX records?

It varies greatly.
