Verizon are known for two things: trying bizarre things to stop spam
coming *into* their network[1], and being one of the world's worst ISPs
for the amount of spam coming *out* of their network. So you might well
want to blame Verizon. I certainly wouldn't expect that even e-mail
coming from a Verizon IP address would be exempt from their anti-spam
procedures.
What is the sender e-mail address for the e-mail? What's the domain
name?
If the domain doesn't appear in DNS, then Verizon are likely to block it
for that reason. (For example, root@xxxxxxxxxxxxxxxxxx).
If the domain *does* appear in DNS, Verizon are likely to try to connect
to the mail server responsible to see if they can send e-mails to that
address. So if the domain name points to an IP address under your
control, but you don't have a mail server on that IP address to which
Verizon's mail servers can connect, Verizon won't accept it.
If the domain *does* appear in DNS and Verizon think they're responsible
for it, then they might decide that the e-mail has no business coming
from that particular IP address.
And they probably have other tests, too.
Because DNS and mailservers are not 100% reliable, Verizon won't
permanently reject e-mails. They'll reject with a "4xx try again"
message. (This is what greylists do -- it's just that greylists will
accept the second time. Verizon won't accept e-mails until you pass
their tests).
That's why you're seeing the 5 day timeout.
Hope this helps,
James.
