Am having problems sending mail from my Thunderbird. I configure the SMTP server to smtp.gmail.com,and smtp.google.com still get error message saying
Sending of message failed.
The message could not be sent because connecting to SMTP server smtp.googlemail.com failed.
The server may be unavailable or is refusing SMTP connections.
Please verify that your SMTP server settings are correct and try again, or contact the server administrator.
How should I proceed?
