Hello All,

in this topic I forgot to mention another android-mail-app.
Thanks to Chris for the hint!

This app is from an austria developer (rundquadarat OG) and called
"R2Mail 2" [1]. It has fully GPG and X.509 (aka S/MIME) support.
This app comes in a test version with limited functions and has a
licence key [2] to buy for full functions. With a price around 5 EUR it
is not that expensive.

The developer was in a parental leave - which i knewed - and should be
back to office now.

best regards
