I had a somewhat heated exchange with their abuse desk about this very
topic.

It turns out that it actually is an anti-spam measure, albeit one
that's almost completely ineffective and has the not altogether
undesired side-effect of pushing people to sign up for their hosting
service.

VZ is still in the process of merging the former GTE and Bellatlantic
ISPs. They know that the correct thing to do is to allow their
customers to send mail with any return address they want, but and
require mail from outside to be addressed to one of their domains.

But their network is a mess and they're technically unable to tell
which IP addresses are customers and which ones aren't.  (This isn't
quite as trivial as it sounds, since there are shared dialup pools
that are sometimes used by VZ customers and sometimes by others, but
it's a problem that other large ISPs solved years ago.)  So they
slapped on the best band-aid they could devise in five minutes, which
was to force the domain on outgoing mail to be one of theirs.

They tell me that when the mess is cleaned up, they should change the
rules to be reasonable, but I have no idea how long that'll take.
