Yes -- as I said, you /can/ do without an MX record if you want to.
However, I recommend that you do always have an MX record: it basically
makes it transparently obvious to people that might want to exchange
e-mail with you that you intended for this host to handle SMTP traffic.
 In fact, even if your mail host uses just the domain as its hostname,
I'd still have

z.com. IN MX 0 z.com.

Which looks entirely redundant, but the reason to have it is more social
and reputational rather than technical.

Given you've an ac.uk address, try finding the O'Reilly Sendmail book in
the library there.  It's a bit of a doorstop, but a lot of it consists
of enumerating various different options -- reference stuff, rather than
instructional material.  Not sure if it's still available to buy, but
that is probably the best guide to Sendmail you'll find.

For quick reference I find /usr/share/sendmail/cf/README is actually
pretty good.

	Cheers,

	Matthew
