  Well, the RFCs say that if there is no MX record for a domain, but
there is an A record, treat the A record as if one had specified it as
an MX host.  A lot of people aren't aware of that when they configure
their www.foo.com domains and see mail attempts coming to their web
server.

  Or just be dumb.  I can see people adding their private address
space servers and wondering why they don't get any mail.  :-)
