Unable to email AT&T domains. Requests sent to abuse_rbl address since 01/21 have gone unanswered.
Back in January of 2021 we switched ISPs and therefore got a new public IP address. After making this switch, none of our users are able to email any AT&T owned domains. We are a medical facility and are trying to communicate with our patients who have AT&T email addresses. We have sent many emails to the abuse_rbl address since 1/27/21 that continue to go unanswered. There are many, many posts just like this and on rare occasion someone from AT&T actually gets involved and helps get this resolved. Therefore we're giving this route a try and crossing our fingers that this will get us further than the abuse_rbl email address.
Currently we are providing instructions to patients with AT&T addresses on how to set up a Gmail account so we can communicate with them via email. Obviously this is less than ideal for both us and for AT&T as we will just have to continue to discourage people from using AT&T services. So if someone from AT&T could please get involved and simply resolve this that would be great.
