Thunderbird does oauth with gmail just fine. We can't do it with yahoo because they just will not issue the appropriate keys. Unfortunate, but something I have come to expect from yahoo. I am not sure what they are good at. But it is not mail.

So is it the messy yahoo flavour or has ATT go their own servers again or have they got yet another contractor supplying their email service. The trouble will answering questions about ATT is they apparently really do not want to be in the email business, so the do a poor job of it and change contractors so frequently and grandfather stuff from old contractors. It is a real dogs breakfast really..

Thanks for your input... Seems like I will be getting rid of ATT email... They have been subbed for years under Yahoo mail and like you said, they aren't interested in providing the service themselves - so we are being forced to agreeing to Terms of Service for Yahoo/Verizon meaning targeted marketing by scanning our emails. Just wish the Gmail would work POP3... Oh well, can't have everything :)

Another provider option is GMX. I have not used them but they come highly recommended by other members of the community. They might be IMAP only since I see no reference to POP. If you are just wanting POP to have a local copy that is what the Thunderbird Local Folders account is for. Here is the GMX site for more info. https://www.gmx.com/mail/email-address/#.2831624-header-subnav1-3

Thank you for the additional information. I liked POP because the emails, once downloaded to my primary computer were automatically removed from ATT/Yahoo Server. I'm old school and don't sync my devices, keep stuff in the cloud, do social media etc... I guess with IMAP I have to go and manually delete from Gmail or whoever, but I guess I can deal with that. Thanks again :)

Be aware if you delete IMAP messages from the server without moving a copy to the Local Folder account they will be gone everywhere. You are just viewing IMAP messages remotely. You delete them on a device or the server they are gone. I just create folders to sort messages to under the Local Folder account and move any message that i want to keep into those folders. The act of moving a message out of the IMAP folder into a folder under Local Accounts deletes the message from the server. I like this better since all the junk I do not want does not get permanently loaded to my hard drive. I move messages I want to keep and then delete the remainder from the IMAP account server.

Two things.

I maintain a Yahoo pop mail account, just to prove it works, not that I use it. Like you I have refused the mail token thing and will continue to do so. whilst ever you keep the use less secure apps setting on yahoo set then you will not have an issue. I assume at some point they will force some further change on us, but I am hopeful that at some point we can get oAuth working. There has been precious little progress, but one day. Perhaps when the purchase settles down.

Gmail also works fine with POP, I get most of my mail from Gmail that way, including mail from this forum. You do however have to go into your gmail settings and allow it before you start trying to add it in Thunderbird, or any other mail client.

This link should get you to the appropriate settings page in your account https://mail.google.com/mail/u/0/#settings/fwdandpop

You will also have to make some changes to the gmail settings to delete mail if that is what you want to do. They basically ignore Thunderbird delete and use the settings on the page I gave you to take action on pop accessed mail

Also make sure when Thunderbird's wizard offers the option to change the default IMAP selection to POP.
