Can no longer deliver mms messages to mms.att.net

Hi, as of a few days ago my company is no longer able to deliver messages to mms.att.net subscribers.  We've been using these email notifications for our customers for many years now and it's been working flawlessly.  We're currently seeing error message: 

 

Deferred: host mx3b.txt.att.net[166.216.152.132] said: 452 4.1.0 <[email scrubbed]> requested action aborted: try again later 

 

Please advise as to what we can do to resolve this issue.

 

Thanks,

Jon Weiss

IT Director of DIY Media Group, LLC

Hi Chris,  I'd really appreciate that!  We're still being blocked as of this morning.  Our IP address is 160.72.46.162 and mail comes from [email scrubbed], [email scrubbed], [email scrubbed] and [email scrubbed].

Thanks so much!  Jon

Chris, here's the error message.  Deferred: host mx3b.txt.att.net[166.216.152.132] said: 452 4.1.0 <[email scrubbed]> requested action aborted: try again later.  This has been happening for about 2 weeks now.  Thanks again, Jon
