Do you have a reference for this (reverse lookups) anywhere? I can see
two different problems with Verizon's mail servers at present, but they
don't include reverse lookups:
1. For outgoing mail, they have stopped supporting AUTH LOGIN (RFC
2554). Given that AUTH LOGIN sends credentials in plain text (well,
base64 encoded) over the network, there is at least *some* justification
for this.
2. For incoming mail, they're blocking much of Europe by IP address. The
google URL I posted earlier has meny references to this, and it's much
less defensible. They're also using a home-brewed sender verification
scheme that can appear at times to be indistinguishable from a
dictionary attack.

I'm quite happy with my own ISP and the services they provide, and if it
wasn't for the fact that I'm such a geek, I'd be using their mail, DNS,
web etc. services. However, I choose not to; I run my own servers for
these services for my domain, and thus do not suffer from any cock-ups
other than my own - I use my ISP for connectivity only. I guess that
would be an option for you too?
Paul.
