K-9 Mail for Blackphone

K-9 Mail for Blackphone is a customized version of the extremely popular open source K-9 email client. The Blackphone version includes enhancements and customizations specific to the Blackphone environment, but you can still find the most up to date and accurate information about how to use it on the K-9 Manual page on github.

If you had installed K-9 on your Blackphone before the customized client became available, please note that the two versions can be used separately.
