About a month ago, Thunderbird stopped working for me. It received e-mails fine; but for the life of me, it wouldn't send one. I kept getting a timeout error when it attempted to hook up to my ISP's outgoing mail server.
I tried changing settings, downloading the newest version - everything I could think of. Nothing. So for the past few weeks, I have been using Verizon's Yahoo page for looking at my e-mails.
Today, just for the heck of it, I sent myself a "test" e-mail, using Thunderbird. It worked! Thunderbird is now working with the Verizon outgoing server again - something healed itself.
Or perhaps it was the dead chicken that I shook at the computer?
