We haven't changed any of our SMTP settings on the server. This morning we were suddenly unable to send out emails with our current From Address. The error we received is attached but I'll reproduce it below:
"Email reply failed from being sent! Momentary issues with the mail server, Try resending this email again."
Trying again only gives us the same error.
We reset the password for our SMTP server and when we try to save the new password in our SMTP settings on Desk the generic error we receive is "Error while processing request!" This doesn't tell us what exactly is going wrong. We know the new password is correct. We haven't changed any SMTP settings prior to this so we don't know why it suddenly stopped working in the first place.
