Verizonwireless.com Blacklisted SMTP

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…

This would be a *lot* more easily debugged if you told us what exact IP
address you tried this *from*.

Verizon (broadband etc) != Verizonwireless

Different mail farms and all

The error returned seems reasonably clear - except for munging of IPs by the OP

Correct, the only thing I pulled out was our particular IP address; I’ve proven this true from multiple box’s on Cogent’s network that are unrelated to my workplace. I did go through that Verizon Online Whitelist procedure, and got a response saying that it has been approved and will be changed within 72 hours, but as someone mentioned before, VOL might != VZW…

Thanks,
Chris

There is no ‘might’ about it; VZ (aka VZ Telecom, VOL, VZBusiness) != VZ Wireless
They are 2 completely different operations and networks.
