Your message states that your SMTP data has been properly entered. There are two options to pass on this Yahoo and Thunderbird or the use of your port numbers can be used for this 465 but also 587 is a good option and is the most popular of today For this network traffic. And password to normal.

Hello there

Your settings should be restored to Thunderbird or updated via the normal method of requesting a new password. Okay, you did this? Is there a way to reverse this?

Most of this is that Thunderbird will work as it should again immediately when it is cleared from an incorrect input of passwords that had to be reset in the normal way.

Hello there

This also applies to the use for your BT Mail.

Your passwords can be reset on the supplied photo. Has this had any effect?

I tried uninstalling Thunderbird and re-installing it but still no good. I still receive the same message as before. Some problem with the outgoing server settings Richard

Sorry but I could not read your photo reply as the text was so small and when I magnified it, it became blurred and unreadable. Richard

Hello there

The situation is that you should change your password from BT so that your BT email program should do it together with the right settings you already had in Thunderbird when it worked.
