Tried that and it works. The minimal public key of multiple UIDs written as autocrypt keydata in my case is 15kB, quite large as mail overhead. I guess there's no way to reduce that somehow? Command line gnupg has filter options like gpg --export --export-options export-minimal --export-filter keep-uid="mbox=f...@example.com" 0xKEYID which ends up with 3kB Ascii-armored per uid. > I've updated the documentation at > <https://muttmua.gitlab.io/mutt/manual-dev.html#autocryptdoc> to make this > specific, and added a section "Alternative Key and Keyring Strategies" to > discuss the ways and caveats of sharing keys or keyrings.

I didn't notice a negative impact on regular mail use. Eike -- OpenPGP/GnuPG encrypted mail preferred in all private communication.
