But those are all special cases.  My question was, why can't I just send an
email to an IP address if I know that there is a mailserver on the other end
that's waiting for me to talk to it.

Les Mikesell just told me how to do that, as I'm sure you already noticed.  So
it actually is possible to do that.

That sums up the question for me.  I wanted to know why it's required to go
through a real MX record and the answer is, it's not required if you enclose
the IP address in square brackets.  Which is interesting information to know.
Not of any immediate use, actually, but still... should a situation arise when
it would be convenient to be able to do that I now know how it's done.
