I have an action setup for a transition where I am sending an email to a valid email address todd@myemail.com and it works fine. I have another action setup for the same transition to send an email to a valid cell phone email address 1234565555@txt.att.net and it does not work. The user that I am sending it to, does have the email address listed as 1234565555@txt.att.net

Why am I trying to do this? The person with the txt.att.net is out on the floor and I wish for him to receive a notification when something happens. 

I did goto my todd@myemail.com account and send an email to 1234565555@txt.att.net and it works fine.

Question is how do I get PDM to send email to 1234565555@txt.att.net?
