• Cannot send encrypted mail

    From Philipp Klaus Krause@21:1/5 to All on Fri Oct 8 11:06:52 2021
    I have setup email enryption in Thunderbird as documented on https://blog.nicohood.de/use-thunderbird-78-with-system-gnupg-keyring
    for four email accounts.
    Two of the accounts have their own key A and B each, which works fine.
    The other two have one common key C (and the key manager in Thunderbird
    shows both email addresses), which doesn't.

    For the accounts that have their own key each, everything works,
    including sending encrypted mail to my other accounts, i.e. using key C
    for encrpytion.

    For the two accounts that use the same key, I can receive and read
    encrypted mail sent to me, but for at least one of them¹ I can neither
    send encrypted mail nor save drafts. I always get an error message
    telling me that the key C cannot be used for encryption.

    ¹ I only tried with one of these accounts, as the other one doesn't work
    in Thunderbird at all - I think the server uses an older TLS version no
    longer supported by Thunderbird or a self-signed certificate or whatever.

    You are not likely to get any support in this newsgroup. It is
    officially dead and although some servers are still carrying it, users
    in other servers can't read any posts. I suggest start using:

    alt.comp.software.thunderbird

    alt.comp.software.firefox
