It looks to me as though Verizon is using yahoo to host their email
services:
mta1012.vzn.mail.ac4.yahoo.com
yahoo has always had some pretty sticky anti-spam rules. My guess is
that they're adjusting some things, and the dust hasn't settled yet.
yahoo has so many mail servers that it's quite possible to see
inconsistent behavior from one message to the next, depending on which
servers process the message.
Trying to send from a different domain/server is a good suggestion,
short of running your own mail server (where you have much more control
of things).
