Could be some DNS issue...
I get this for verizon.net:
verizon.net.
nameserver = ns2.verizon.net.
nameserver = ns2.bellatlantic.net.
nameserver = ns4.verizon.net.
nameserver = ns1.bellatlantic.net.
0, relay.verizon.net.
relay.verizon.net.
206.46.232.11
sv5pub.verizon.net.
alias = vms141pub.verizon.net.
vms141pub.verizon.net.
206.46.252.141
I don't see why SMTP is sending to sv5pub.verizon.net, unless
that is part of the address you have for the recipient (which may
be wrong!).
When I connect to relay. on port 25:
220 sv1pub.verizon.net MailPass SMTP server v1.2.0 -
112105154401JY+PrW ready Thu, 6 Jul 2006 12:19:29 -0500
I cannot connect to sv5pub.verizon.net on port 25...

Subject: [IMail Forum] Verizon problems
Morning all
Last week, I found I was unable to send to a Verizon customer. I
was getting "550 You are not allowed to send
mail:sv5pub.verizon.net"
I submitted our mail server IP address to see if we were
blacklised and got a reply back that we were not.
I then switched to using a Charter SMPT server and got a similar
response.
I next tried using remote access, web mail on the our Imail
server so there would be no record of a dynamic IP address in the
header and sent another message.
It timed out this morning with "421 SMTP service not available,
closing transmission channel" and terminating after the Imail max
tries timed out.
Does anyone have any thoughts, as we speak, none of our customers
are now able to email anyone at Verizon.
Thanks for any help.
John
