Inability to send e-mail via Thunderbird
After more than five years of successfully using Thunderbird to send and receive e-mail, I have been receiving the following message for the last couple of weeks when trying to send an e-mail:
Sending of the message failed.
The Outgoing server (SMTP) smtp.cox.net does not seem to support encrypted passwords. If you just set up the account, try changing the 'Authentication method' in 'Account settings | Outgoing server (SMTP)' to 'Normal password'.
Does the Cox SMTP server no longer support encrypted passwords?
