Hi,


     What's up with VZW blacklisting a large amount of IP space on their
MXes? I have tried sending mail to verizonwireless.com from several boxes on
Cogent's network to no avail... Is Cogent on the "bad boy list" yet again?
Anyone have a useful contact there? We're not able to correspond with our
sales rep via email and they're losing business. I have contacted some NOC
engineers with no luck... 

Trying 162.115.163.69...
Connected to mars.verizonwireless.com.
Escape character is '^]'.

554-Your access to the VZW mail systems has been rejected due to the sending
MTA or Network Service Provider's poor reputation  / e-mail hygiene on the
Internet.

recipient via alternate means. 
Connection closed by foreign host.


Thanks,

Chris
