So that's not the problem.  You're supposed to be able to get the blacklisting fixed 
if you email abuse_...@abuse-att.net  but I've 
emailed them from 3 different addresses and have yet to get a response much less a 
resolution.

Has anyone else had to deal with this bullocks and gotten it resolved?


That has never worked for me.  I've only been met with radio silence.

You can ask them to create a PTR for your static IP and hope for the 
best.  Most I have dealt with will do it as long as it's a commercial

As I pointed out - but failed to copy/paste a couple extra lines - 
cableone have issues, earlier they were reporting SERVFAIL then it was 
unreachables.


The fact OP showed google knowing his PTR. says he should not have to 
have them add it manually, they need to fix what they already have - or 
they need to pay their bill :)


It's also why we dont accept reports here that " oh google says its 
there" because google have a history of not honouring TTL's, and it 
always pays to use a DNS server that you don't think would have your 
zone cached, to get a fresh perspective.

NO PTR for the IP.

Cableone is SOA on this zone, so they are the issue.

You can ask them to create a PTR for your static IP and hope for the 
best.  Most I have dealt with will do it as long as it's a commercial 
account.
