AngelRicardo, I'm not sure where you are in the world, but in the U.S. Yahoo Mail IMAP access is not free. You have to pay for Yahoo Mail Plus to have that option.
===== CRS, What you suggested about logging in to the web interface and sending a test email worked for me. Once you fill out the CAPTCHA, your TB/ Webmail/Yahoo will work again for sending. Thanks. :) Regards all... ~Eric
