**** For folks seeing a performance regression on 4.4 ****

Some longtime users of K-9 have reported incredibly slow message display times in 4.4. We haven\’t yet gotten our hands on a device that exhibits the problem, so we haven\’t been able to develop a proper fix. One thing that has worked for everyone who\’s tried it is so far to long-press on the account name in the Account list and select \”Recreate Data\” — This will COMPLETELY ERASE the local copy of your mail and redownload a brand new copy of everything from your server. Be aware that any mail that\’s on your device but not on your server will be DELETED.


K-9 Mail is an open-source e-mail client with search, IMAP push email, multi-folder sync, flagging, filing, signatures, bcc-self, PGP, mail on SD & more!

K-9 supports IMAP, POP3 and Exchange 2003/2007 (with WebDAV).

K-9 is a community developed project. If you\’re interested in helping to make the best email client on Android even better, please join us! You can find our bugtracker, source code, mailing list and wiki at
We\’re always happy to welcome new developers, designers, documenters, bug triagers and friends.

If you\’re having trouble with K-9, please report a bug at rather than just leaving a one-star review. We don\’t mind you telling the world that you\’re frustrated, but if you use our bug tracker, we have a better chance of fixing whatever\’s giving you a hard time.
