We cannot react on that! If you get errors please use "Menu -> Report Error" on the start-screen to send us the log-file information in your preferred way! Informations about Private Key and Validity Handling: The application comes without a personal key pair (the users private and public key) - so it is fully functioning in the sense of sending and receiving emails as any other mail client and provides the correct usage of validation if the mail you receive is signed by the sender. For signing or encrypting a message it is necessary to use a private key you own. Turn to a Trust Center of your choice as a source of supply. You can find a list of trust centers, which are trusted within the Android world, in the Certificate Store (CA section) of R2Mail2. Please be aware that this app can only support Soft-Token in form of P12-files and will not work with smartcard-based certificates. For more information visit http://r2mail2.com

FairEmail, privacy aware email

FairEmail is easy to set up and works with virtually all email providers, including Gmail, Outlook and Yahoo! FairEmail might be for you if you value your privacy. FairEmail is simple to use, but if you are looking for a very simple email app, FairEmail might not be the right choice.

FairEmail does not support non-standard protocols, like Microsoft Exchange Web Services and Microsoft ActiveSync. Almost all features are free to use, but to maintain and support the app in the long term, not every feature can be for free. See below for a list of pro features.
