So just today we are seeing where text messages are not being sent through the 2019EX server.
Between yesterday and today I disabled several recieve connectors.
However they appear to be configured the same.
Error messages include:
"451 4.2.0 <email@example.com> server temporarily unavailable AUP#SNDR(at END OF DATA)"
"421 temporary failure for one or more recipients (phone numbers) server temporarily unavailable AUP#SNDR)"
450 4.4.318 Connection was closed abruptly (SuspiciousRemoteServerError)
I am unsure how to proceed in resolving.
Open to any suggestions.
I looked at Certificates, I looked at receive connectors...all appears fine to me. <-- This was done through the EAC.
Is there something I should be reviewing via the management shell?
