I've got a Yahoo mail account (among others) that I use for a
particular purpose. However it's been a while since I've been able to
send e-mail from it using Yahoo's smtp servers. Instead I've been
sending e-mail via another smtp server so the "From" address doesn't
match the login domain. Gmail apparently now considers that to be
sufficient reason to bounce the e-mail so I've been trying to get
Thunderbird to use the Yahoo server to send mail for this account.
So far I haven't been able to come up with any combination of
settings, including removing the account and recreating it in
Thunderbird, that allow the mail to go through.
The messages I get either complain about the password or tell me "An
error occurred while sending mail. The mail server responded: Request
failed; Mailbox unavailable. Please check the message and try again."
Does anyone have Thunderbird and Yahoo working together?
Pretty sure, it's the issue with Yahoo¹ ², nothing to do with Thunderbird.
Yahoo is following the same path as GMail, forcing their users to use
web browsers as mail clients.
In case of GMail you have to use same generated "app-password" for both
IMAP and SMTP services.
I guess the same principle will be for Yahoo.
