I'm attempting to get Thunderbird 16.0.1 set up as my email client on a new laptop. I can receive mail but can't send. Doing some research, this seems like a common problem, but none of the suggested solutions have worked for me.
The first error message I encounter says: "Login to server mail.shaw.ca failed" Choosing "cancel" brings up the message below (other options are "enter new password" and "retry" but both loop me back to the same error).
Sending of message failed.
The message could not be sent using SMTP server mail.shaw.ca for an unknown reason. Please verify that your SMTP server settings are correct and try again, or contact your network administrator.
Here are the settings I'm currently using:
Server Name: mail.shaw.ca
Authentication Method: Normal password
Connection Security: STARTTLS
Any help would be greatly appreciated! Thanks!
