Cox Blocking T-Mobile IP Address

Is anyone else having issues with cox server blocking t-mobile email ip address?  My cox email is on my phone using K-9 mail and it was working just fine the other day but now i cannot send messages using the T-Mobile 3/4g network.  i can send using my wifi.  i receive the following message "Cannot connect to server. (554 fed1rmimpo110 cox connection refused from 206.29.182.129)

I would go through and check your settings on the phone itself for the email server. I just tested on my phone and its working just fine.

Yea, I actually have a friend with the same issue and an ip address in the same range 206.29.182.XXX. So far we have determined that the Tmobile ip range is on a block list for a spam/ botnet trojan issue. We cannot send as well and will be calling Tmobile to get them to fix the issueor assign a new ip.  I checked your ip and its listed as well. You may want to call them and report the issue.  Here is the site that list the ip as a problem http://cbl.abuseat.org/

I am having the same issue. it started yesterday afternoon. "Your outgoing server response:

544 fed1rmimpo210 cox connection refused from 206.29.182.183" . Did anyone get any resolution? Or get any assistance from Cox and T-mobile? This is alway fustrating when you have done nothing but  use your phone equipment for work and it just stops working. this cost a business time and money and there is no assistance to fix their problem. Can anyone direct me to a solution. I did go to the linked CBL web page and the above IP was not on the list according to the web page.
