Both my wife and my computers receive this message [ 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'. ] when we try to send email. Occurred with both computers about a week ago. 1) Checked settings: all accounts set for normal password. 2) Checked with Cox (internet provider). Was shown that using web mail that I could send email through smtp.cox.net. 3) Reinstalled Thunderbird. No change. 4) No viruses or problems found by protection software. Still receiving email on 5 accounts with no problem but we can not send from any of them. Unsure of where to proceed except switch email software. Ed
