there is no "Edit" button within the Certificate Manager in the People register. So I'm wondering what you trying to do. You only can adjust the trust to CAs globaly. That's something totally different to Certificates for persons. > Because of this problem I am not able to send S/MIME encrypted mails any more > to this persons.

Without that encryption can't work because the trust chain of the certificate can't be resolved. http://kb.mozillazine.org/Installing_an_SMIME_certificate > I can reprodoce this problem on more computers and also on a clean > installation. Please note that S/MIME is more or less broken by design and future version of Thunderbird/Icedove maybe will not have S/MIME support implemented. Mozilla is thinking about removing the S/MIME part from Thunderbird. https://bugzilla.mozilla.org/show_bug.cgi?id=1178032 Regards Carsten
