PROBLEM ======= * Hi, OpenPGP can't send encrypted emails for alias emails, even though keys for master and alias accounts are imported. But the do send and receive fine without it. * Every key I have is able to encrypt, sign, and decrypt. So I don't have missing parts, as they were just made. * Version = Thunderbird 115.61 (64 bit), Flatpack on Linux 22.04 EXAMPLE ======= I have a domain email with multiple aliases in this format: A@A.com = master account. B@A.com = alias C@A.com = alias. The one I want to encrypt. It's setup properly in Thunderbird. All 3 use the same login / password as A@A.com. They all send / receive regular email just fine. So I went to Account Settings > A@A.com > End to end encryption > Add key > Import an existing OpenPGP key > select the private key (C@A.com) > Treat it as a personal key (on) > unlock it with the password > It says "OpenPGP keys successfully imported" in a green box as if it loaded properly. But when I go to send an email with C@A.com, the ''Encrypt'' and ''OpenPGP'' buttons up top are greyed out, meaning it can't send or save encrypted. BUT!!! When I make a key for A@A.com (master account - remember the others are aliases), and do the above: it's finally available to select in the End to end encryption spot... And then I can encrypt things for A@A.com just fine... '''Which tells me that it will only accept master account keys, not aliases.''' But C@A.com won't work, which is what I want. C@A.com won't even show up in the end to end encryption spot ''(likely because it's an alias).'' Tools > OpenPGP manager = my keys all show up just fine too. QUESTIONS ========= 1. Any ideas on what's going on / how to fix this?? 2. Why are only master account keys working? If anyone knows the answer, thanks. This is been pretty aggravating, as this used to work fine a year ago or so, but not anymore for some reason.
