We have the same issue (our mail server IP address is 22.214.171.124)

Cloudmark say our server is not listed as having a bad reputation
Submitted IP Address is Not Listed in Cloudmark Sender Intelligence
The SMTP rejection that you have received is not the result of current data provided by Cloudmark Sender Intelligence.

An abuse engineer will investigate and respond to you within one business day. Requests that do not contain an error message or time-stamped log entry will not receive a response.

TalkTalk normally blacklists sending IP addresses or domains if multiple customers have marked emails as Spam or you're sending to multiple talktalk managed email addresses that are not active.
The sender IP address you've quoted is on the TRUNCATE blacklist. This is an auto-created blacklist populated by IP addresses that have been detected as involved in sending spam. There is no removal process for this blacklist but the entries do auto-remove after, usually, a period of 2 weeks if no further 'spam' is detected.
The usual advice is to regularly check that all mail addresses on your mailshots are willing recipients.
I'll alert the TalkTalk Community team for you to see what can be discovered from the TalkTalk end.
In the meantime, please update your Community Profile Personal Information (Click here) to include your name, current contact 'phone numbers and address with postcode (location) then scroll down and add the sending email address to Private notes together with some examples of talktalk mail addresses on your mail list and then Save changes.
