MX records are not required. I remember reading somewhere - possibly
even on this list - about exactly that. Try setting up a domain
without one and then use the mail :-)
Right, if there's no MX record the MTA is supposed to fall back to looking for
an A record. In fact, until a couple weeks ago the domain I'm sending from
right now had no MX record, mostly due to laziness on my part.
An MX record is just a way to say "do not deliver directly to this host,
use that other host instead".
So, instead of saying "fall back to the A record", IMHO you should think
of it as "there's no MX record overriding the A record".

I ask you to respect any "Reply-To" and "Mail-Follow-Up" headers. If
you reply to me off-list, you'd better tell me you're doing so. If
you don't, and if I reply to the list, that's your problem, not mine.
