Chris,
Maybe I can explain better - sorry.
I happen to be a cox subscriber and have an account (this one).
I also work for a SAS software company (prodbx.com) that uses an email server (maildbx.com) tied to our system that our clients use to communicate with their customer base.
Recently, Cox started blocking emails from my company's email server (maildbx.com) prior to any individual spam filters. I happen to know this because I also personally happen to be a customer for one of prodbx.com's clients and I stopped getting emails from them.
This is how I found out that the emails were getting blocked.
My huge concern is that we are NOT blacklisted in any RBL list, yet cox (only provider that we are aware of) is blocking us.
We checked our server stmp logs and indeed verified that cox is blocking our maildbx.com emails - This note is from one of my developers:
Jeff, I was able to check the smtp logs on the server and cox is indeed blocking the maildbx.com emails... I found this page: http://postmaster.cox.net/confluence/display/postmaster/error+codes where the cox postmaster error codes can be checked. We're getting the IPBL1000 code which says the following: "The Sending IP is listed in the Cloudmark CSI DNSBL". I checked here: http://www.anti-abuse.org/multi-rbl-check-results/?host=maildbx.com and according to this site we're not being listed in any RBL list so I'm not sure what's going on.
Are you able to assist me with this or is there a way for me to open an official ticket?
Any help is greatly appreciated.
