I have a problem as follows: If I import a private or public COMODO SMIME certificate in Kleopatra (pgp4win keystore), the key is marked as “Not valid”. As long as the keys are marked as “not valid”, it is not possible to send SMIME-mails via Outlook using the PGP-plugin.
Only if I deactivate the CRL-verify in Kleopatra it succees, but this not a good solution. No problems with SMIME certificates from the ACTALIS CA, they are “valid” in Kleopatra!
Do I have to download the CRL-File from Comodo and to manually import that file in Kleopatra? But I dont find the CRL-File from your website.
