Hi, this is the second Debian distro that I have been using that kmail 2 refuses to show Yahoo! Mail email account content on the left section of the application. I don't know if this is Debian specify. I did set it up correctly, but nothing. I did use the account wizard to fetch online settings for each email provider. I have two accounts from two different email provided, one of which is Yahoo!. The other mail account which is imap also, shows up just fine. But no show with Yahoo! I did use Kmail 1 previously which showed the Yahoo! account without problems and with the same settings for imap. Akonadi resources configuration shows the Yahoo! account setup, but it does not say "ready".
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
