Connect to yahoo mail fails: [SYS/TEMP] internal server error (#OCF013)
Had this problem around beginning of December 2016, then appeared to clear up by itself. Note that this correlates with the latest Thunderbird version 45.5.1, dated November 30 2016. Problem reappeared about 12/21/2016. Have email through frontiernet.net. Have spent much time with their tech support, deleted/recreated email account with settings recommended by frontier tech support. Same problem. Have seen that many others are experiencing the same thing. FYI, can see emails using firefox to log in to email account, so I know email address and password are OK.

have you enabled the less secure apps setting in your yahoo account settings on their web site?
Aaaargh! Thanks for you reply, but I spent almost two hours on the phone with frontiernet tech support on this. He recommended the same thing, but try as we might we could not find that setting anywhere. It might be because it's a frontiernet account supported by yahoo, not direct service from yahoo to me. Is this something you have to do from a smart phone instead of from a laptop?
All I can do is point you to the Yahoo help page and another that has better images

We did try to make Thunderbird able to use the oAuth2.0 authentication. But yahoo are not playing the game, instead blocking the ability of mail applications to create keys to access their mail system.
Bug report for Thunderbird here https://bugzilla.mozilla.org/show_bug.cgi?id=1293958 In the bug you can read the frustration of all concerned. Basically they have been stonewalling their own developer community for months, not answering mail and generally pretending Rome is not on fire.
