Ahoj, Thunderbird mi u vsech zprav ktere jsou elektronicke podepsane hlasi ze podpis neni platny ale to je chyba. V ostatnich klientech(Outlook, EMclient)se podpis u zpravy zobrazi jako platny. Stejne tak kdyz chci odesilat s elektronickym podpisem. Nejde to. Mam nastaveny platny kvalifikovany certifikat pro spravny mail ale nemohu odesilat ani elektronicky podepsane ani sifrovane. Zkousel jsem to i na jinem PC, v jinem uctu windows ale problem je porad vsude stejny. Ostatni klienti nemaji problem ani pri odesilani. __________________________________________________________________________________________________________________ Hi, Thunderbird tells me that the signature is not valid for all messages that are electronically signed, but this is an error. In other clients (Outlook, EMclient) the signature is displayed as valid. The same when I want to send with an electronic signature. It doesn't work. I have set up a valid qualified certificate for the correct mail, but I cannot send either electronically signed or encrypted. I have tried it on another PC, in another windows account but the problem is still the same everywhere. Other clients have no problem even when sending. Translated with DeepL.com (free version)
