 Don't use instructions for windows.

The instructions I found--this was a couple of months ago, and different of course, said it only works in Windows, and it did. Once you get T'Bird working in one spot, it works everywhere.

 I don't think you will be happier with KMail.

I was happy with T]Bird until it lost its mind again.

 Look. Open Thunderbird.  Edit / Preferences.  Search for "passw" (there is a search box, top-right).

 You will see a button for "Saved passwords", click that. Search then for the one or ones you want and simply delete them. Or remove all. You can also display them. Once done, close that dialog, and verify that you have defined a Master Password. If not, do create it now.

 Or is it the master password the one you forgot?

Up to now, I didn't use a master password. I erased the only password it showed. I was not using a master p/w, but now I have added one. It still asks for a password (after entering the master password) and it still refuses to use a password I was using, and it still asks for and ignores any new password I enter. And one of its complaints along the way--it didn't know my mail server, altho it is in the program somewhere and showed it along the way.

 I don't know if there is a way to regenerate a forgotten master password, but my guess is, you have to first erase all existing passwords, then try disable "use a master password".

 Otherwise, I would create a new Thunderbird profile and start over.

Well, I'm certainly willing to do that. How can I get rid of everything that's there and start over? Is there an omnibus command like zap thunderbird? Probably not! (I don t want to start the OS over! Thanx for the input--still beating on this terrible optimum routine.

I highly suspect that your problem is not with Thunderbird, but with that stupid mail server / provider of yours. Thunderbird should: - Ask ONCE for the master password once you open the program the first time. - Ask ONCE in life for the password of your mail account the first time it tries to use it. Once for receiving, once for sending. - If the SERVER says the password is wrong, Thunderbird will ask for that server or account password, and will ask a thousand times till you give it right - ie, the server says it is right. You can hit cancel or ESC, probably. - Once the SERVER accepts the password you typed, Thunderbird will save it and never ask for it again in life. Ok, certainly there are easy ways to delete the entire Thunderbird thing, but you don't need to do that. Just create a new mail account for your mail provider. Just give it a different name than the one it has now. Thunderbird can have dozens of accounts defined. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
