I know this is an older thread.
I have used the native email notification agent for years. I have it sent to my phones (email address) so it arrives as a txt. It has worked faultless for years.
Recently it started acting up. The messages still go thru, sometimes immediately and other times delayed by 20min, 3hrs, or whatever. It logs the correct event time.
No changes in my system. Same router, modem, etc. Director is on 3.1.3.
Have rebooted EA5.
Phone service was Sprint, now TMobile(bought out Sprint). I have tried sending to 000-000-0000@sprint.messagingpsc.com and 000-000-0000@tmomail.com
Any ideas?
