I have had good success with Thunderbird until this morning when, posting a second email with photos to my wife, I got the message that the server connection timed out. I called my email internet provider locally, suggested to uninstall and reinstall, to check configuration. None of that worked. I modified one setting, the name of the outgoing server, when I checked with the protocols provided by the email/internet local provider. That also didn't help. I'm at a loss.

Thanks if you can help.
