I have verified that all server (SMTP) settings are correct. Again, messages arrive, but don't send. When prompted for a password, I enter the correct pwd (yes, I checked) and get:

"Login to server smtp.gmail.com failed." and "Sending of the message failed. The message could not be sent using Outgoing server (SMTP) smtp.gmail.com for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again."

I can login to google via browser without issue.
