--- Comment #1 from Stephan Wezel <s.we...@web.de> --- Additional information. When I click on the <keyfingerprint> link inside the details message "Message was signed on <date> with unknown key <keyfingerprint>" an kleopatra window opens and shows the correct gnupg key/certificate. It seems that only kmail cannot find the correct gnugpg key/certificate via an gnupg subkey fingerprint -- You are receiving this mail because: You are watching all bug changes.
