On 6/21/11, there was a Thunderbird upgrade to version 3.1.11. Since this upgrade, Thunderbird will not download messages from the Yahoo! mail server. Has anyone experienced this and possibly found a solution? No problems prior to the upgrade. Now it says Connected to pop.mail.yahoo.com, but never downloads and there are no error messages. I know this isn’t “officially” supported, but I am sure there are others that use Thunderbird. Thanks.
Maybe this has something to do with it.
This list covers some of the known problems with Thunderbird 3.1. Please read this before reporting any new bugs.
Your passwords are stored in a new location. If you go back to using Thunderbird 2 or switch back and forth between Thunderbird 3.1 and Thunderbird 2, your password lists do not get updated.
I use the same version of Thunderbird, and when I switched to AT&T Uverse, it took me a week to get my EMAIL working. I never did get any help from AT&T, I had to figure it out myself.
I think My problem was server settings, but I did delete all my passwords and start over again.
My server settings are incoming server pop.att.yahoo.com port 110. Outgoing SMTP server smtp.att.yahoo.com port 25 connection security, none.
