I have just had one of those annoying wastes of a couple of hours when something which worked on my computer suddenly decided not to, for no apparent reason.
In this particular case it was that my e-mail client, Mozilla Thunderbird, suddenly decided not to send e-mails. It would receive them fine, but not send them. Instead, it would display a pop-up box asking for the password to the server, but when I entered it, it simply repeated the request. If I cancelled the request, I got a message saying it could not connect to the SMPT server.
I tried the Thunderbird Help Forum, and Googling things like "Thunderbird cannot send e-mail asks for password", and all combinations in between. I found numerous similar complaints and requests for help going back over the years, all from people who'd been using Thunderbird and who suddenly found they could receive, but not send, e-mails, and that repeated attempts to enter the password were refused.
Well, I finally worked out a solution. I am not sure if it is a wise one, but it works for me, so along with my advice on Installing FAX services for Windows XP, I offer it as a 'public service'.
1. Open Thunderbird
2. From the menu bar at the top, click Tools> Account Settings> Outgoing Server (SMPT) [from left hand menu in the new window]
3. Highlight the account currently in use (or the one you wish to use) and select Edit
4. In the box which opens, under Security and Authentication unclick Use name and password
5. Click OK
6. Try sending again
It works for me. If it works for you, leave a message.John Richardson
(PS: I just tried doing the reverse on my wife's computer, setting it to use the name and password, and sure enough it locked up. I have set it back!)
