I cannot say I understand the specifics, but you would be
surprised how common such problem can be.  I know of a large southern NH
school district which had a broken MX record.  A mail list I run
constantly unsubscribed everyone from that district for bounces and they
complained that something was wrong with my mail system.
I had to send them the info from running host on their domain to show
them the busted MX record.

So if Verizon will not accept mail that does not validate with reverse
lookup it bounces, right?  So no reverse lookup, mail will bounce from
anyone who does reverse lookup.  Since not everyone does, some work,
some do not.  Have I got that right?
