outgoing e-mail

I am using v. 91.9.1 of Thunderbird e-mail

I have been running 4 e-mail addresses, all with BT.

This last week 2 of those addresses have stopped sending outward messages although I haven't changed anything in Thunderbird or BT.

The other 2 addresses work for both in & outgoing mail.

On the failed outgoing mail I get the following message:- "Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'." BT says they can't help. The problem is with Thunderbird??

Any ideas ? Regards David Bates

Hello there again.


Since it has the issue to not send messages. Something’s wrong at the settings. Check all Smtp settings for your mail activities.

Check and change if that is possible the password s for pop and Imap

Go to Tools > Preferences > Privacy and Security > Click on Saved passwords then click on Show passwords. Right click on the password you want to change and click on Edit password.

Check in meanwhile the Smtp settings for your Software. Are you using security software for protection? Also with add on?
