@AAMfP@k9mail@thunderbird Interesting offer by #posteo. Just tried in #firefox on my #debian pc and it failed with "Action not permitted" when trying to download the files (I guess). I would also much prefer to upload my own CSR that I generated outside of the browser. BTW, in Germany #ausweisapp enables you to sign your PGP/GPG key by an official authority for free. OpenKeychain works nicely in #fairemail. #kudos to #dhl for using #smime to sign their mails.
