Our county volunteer fire association uses mms to augment a limited number of pagers and get emergency notifications out to volunteers.  Over the past several years this has been accomplished by a relatively reliable software system.  However, this year has seen a marked uptick in the number of delayed/permanently failed notifications sent to volunteers using Verizon.  Below is a example of the error message being received......

"Original-Recipient: rfc822;
Final-Recipient: rfc822;
Status: 452
Action: failed
Last-Attempt-Date: 6 Jun 2024 13:13:20 GMT
Diagnostic-Code: 4.1.0 <email address> server temporarily unavailable AUP#MXRT
Remote-MTA: dns;"

Based on local research, the problem seems to be with Verizon's (and/or cloudfilter's) servers limiting/blocking the messages.  Is there some way to get Verizon to rectify this  as these are not SPAM, but emergency notifications?
