is bind needed at all?

Add to that the fact that in this case, the domain in question does
not really matter. What does matter is how it is delegated; and that
can quite easily be mentioned without the domain name:

	@ NS ns1.myisp.com.
	  NS ns2.myisp.com.

See? No mention of my domain at all; only an imaginary ISP's name
servers.

To answer the original question - no, you don't *have* to even have
DNS access on the mail server; though it could prove useful. How you
get that DNS access - through a local caching resolver or directly to
your ISP's (or, God forgive, someone else's) DNS servers does not
really matter.

What is interesting is whether the MTA can resolve domain names or
not. If you send outgoing mail through this server, it has to be able
to perform at least MX, ANY and A queries; if you receive mail, I
belive tat many MTAs require that those same queries can be asked
about the sending domain - but this behavior can be turned off. (In
sendmail, it's "FEATURE(`accept_unresolvable_domains')" in the .mc.)

So yes, you should have some form of DNS access on that box. How,
though, is not really an issue.
