I don't use Two-step verification in my account. I also tried to use the Yahoo Mail smtp and imap details to connect to a "custom server" with no success.

I also tried this: https://help.yahoo.com/kb/generate-third-party-passwords-sln15241.html (I don't know what should I write at "Enter custom name", when generating password for an "Other app" - I tried with "Elementary") and used the generated password. Same error happens.

Some advices? Thanks!
