This is probably a spam filter. The idea is to reject "rapid fire mail
server" style messages, which are sent directly from dialups, and only
accept mail from machines which appear to be mail exchangers. I believe
this is misguided.
>??? What is this poop? Since when do hosts HAVE to have MX records?
It's a common bug for some MTA's to be confused and unable to talk to a
host without an MX record for it.
>macro.stanford.edu most CERTAINLY has an "A" record. Why isn't that good
Probably because the filter is a bit stricter?
