I've been using this feature for over 2 years, now as of last Thursday, it fails.
Sending a short message to my ATT phone, here's an example of a test message from one of the unix based systems, I've been using:
$ echo test |mail -s "a test" -v 5551234567@txt.att.net
5551234567@txt.att.net... Connecting to mx.txt.att.net. via esmtp...
5551234567@txt.att.net... Deferred: Connection refused by mx.txt.att.net.
So, it looks like the ATT server is now refusing my connection
Note, I get the issue trying to use mms.
Anyone else having this issue ?
