Yes, this is their silly callback-system which doesn't understand temp
fails.  I filled out the form at:

http://www2.verizon.net/micro/whitelist/

And I never saw a reply.  But our users stopped complaining and I do
see mail going through to Verizon, but still the occasional temp fail
from their server for load being too high as well as the callback
temp-fail.

Who is in charge of the mail infrastructure at Verizon?  I am
agressively anti-spam, but callback introduces a host of problems of
which intolerance of the RFC requried temp fail is one of them.  They
need a reality check over there...
