Per-contact signing & encryption preferences (S/MIME vs PGP)

[ghalse]

I use a combination of PGP, S/MIME, and cleartext emails depending on the recipient. Those in the Microsoft world tend to prefer S/MIME because it's already integrated, whereas much of the open-source community prefers PGP. And others can't handle signed email because their corporate mail systems break the signatures or worse, treat this as spam.

At the moment I need to keep the recipient's preference in my head. Do they need signed or unsigned mail; do they prefer S/MIME or PGP; etc. As I get older, that stops scaling well 😉 and it would be nice of Thunderbird's address book could remember this for me on a per-contact basis.

There was an add-on that partially achieves this (https://addons.thunderbird.net/en-us/thunderbird/addon/security-settings-from-addr/) but it doesn't remember the PGP vs S/MIME preference. It also stopped working as of TB78. If I recall, this also used to at least partially work in the days of Enigmail, but doesn't seem to have been ported when Thunderbird got native support for PGP and/or the address book UI got revamped.

It'd be really nice if Thunderbird's address book included native support for this preference.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Yes, that would be nice!

Maybe even per contact ... key selection.
