Extreme incoming email delay or undeliverable
I am seeing 10-20 hours delay in receiving TFA emails, or not receiving them at all, from @tmcaz.com and delivery failure due to taking over 24 hours for emails from @arizona.edu
How can I get this...

Sender or Recipient 'email address'?
And since I do not run the servers, how should I know/find out the 'IP/CIDR range of outgoing email servers'?
Just refer them to your post or include the text of the rejection email in your response. I'm thinking that should tell them everything they need to know to address the problem.
