It supports multiple accounts, search, IMAP push email, multi-folder sync, flagging, filing, signatures, BCC-self, PGP/MIME & more. Install OpenKeychain along side it, in order to encrypt/ decrypt emails using OpenPGP.

  • Corey Bryant (04 Jun 26)

    feat(ci): automate versionName bump for point release in shippable builds Adds pointRelease to workflow_dispatch to optionally bump the point version (e.g. 21.0 -> 21.1). Additionally, rearranges the order of worflow_dispatch inputs to put pointRelease and skipBetaBump at the top, as they are the more commonly used inputs.

    chore(ci): Set max code for shippable builds to Android app max The previous checks aren't really necessary and tend to slow down progress with failed builds that require bumping the max version code. Let's just check for the actual max Android version code instead.
