Verizon.net / Blacklisted
Cox / Northern Virginia.
We have 6 cox.net email addresses which are all on the same account.
Our problem is that when we send emails to Verizon.net they just disappear. There are no bounce backs, no error messages. Nothing at all.
I called cox but they were no help at all. I haven't called verizon because I don't have an account there.
The other day I filled out verizon's whitelist form to see if I was being blocked and the reply was that I was not being blocked. The form is http://my.verizon.com/micro/whitelist/RequestForm.aspx?id=isp
Now I was a little confused about the SMTP Server IP address. I used 2. One I got by pinging dc.dc.cox.net, which I got from IP config, and the other I got from ( I can't remember). Both came back as not being blocked.
Please note: we use openDNS as our DNS server.
My questions are:
-Does anyone know of a solution to this problem?
-How do I give verizon the correct SMTP IP addy?
_ any other suggestions?
Also....we are not doing any spamming or anything unusual. One of the accounts is used for business but it's nothing out of the ordinary. No mass mailings or anything like that.
