Hi,
I just migrated to a new server and currently all the cPanel alert and notification emails are stuck in the mail queue. When I try to force send one, I get a sending error. I also tried changing "nobody" and "root" on the "Edit System Mail Preferences" page to [email protected] and [email protected] thinking maybe it was either a Google or Microsoft email issue.

Not sure what else to try. Any help would be greatly appreciated.
