Until fairly recently one of my hosts was a name server for
verylargedomain. One random mail server kept trying to send mail
through that name server, eventually I tracked down why. They were
using some extremely old mailserver package (unfortunately I don't
remember the name) on a Mac that would try to send mail to _any_
record for a domain - A, MX, NS, etc.
This was still happening 6 months ago when that NS record went
away. Really broken things are still out there.
