I use the Telus email to text server (10 digit phone firstname.lastname@example.org) to receive alarms for my homes' security system. Prior to August 2020 the messages would be delivered within a minute. However lately the messages don't always deliver within a normal time frame. Sometimes it can take hours to receive a message. Is the Telus servier thinking these messages are spam and delaying the delivery until the message is approved? Or don't Telus make some other adjustments to this server?
