That's not a message from QuickEmail.
Are you logged in as the admin Super User?
ModX 2.4.2
QuickEmail 1.1.1
I'm having the same issue. I get an "Unauthorized" page.
Nonetheless, mail service works when sending user credentials but not when executing FormIt.
@dubbs, can you provide further details on how you fixed this? Not sure how to configure ModX mail service to use something other than SMTP.
Thanks!
