I can't send any emails from my school account.
Hi,
I am having an issue where I am unable to send emails on the mail app from my school email. A message comes up that says the email cannot be sent because the server for [my email] can't be relayed. I didn't CC myself in the email. I reset my signature to default because it had my email in it. I cannot diagnose the problem. Any help is greatly appreciated!
iPhone SE, iOS 10.2.1
