If all you're going to do is send mail to person at machine ... no, it
doesn't; but it saves a lookup in some versions of sendmail.
If you're going to do mail to person at domain, then you should have an MX
record.

OK, so you DON'T have an MX record [it is commented out]. Is it any
wonder that mail to foo at www00.com doesn't resolve? That is done by the
MX record. Or would have been.
OBTW, this agrees with a check I had just done [before the Sun repair
guy showed up] that showed no MX record for www00.com.
Why did you show a fake zone file before? Really deflates any
enthusiasm for helping you. How do we know you're telling the truth
THIS time? ;-/
OBTW, the MIT NS contradicts what the root servers tell me. They say
cube.com.
