Importing an attached PGP key from a received mail is not possible currently. The key is displayed correctly as a pgp key and a link to import the key is offered. Clicking on that link doesn't do anything, though. I couldn't find any way around it, like a way to save the key to the harddisk. In encrypted mails, not even the mail source code helps. I don't have debug symbols available, unfortunately, so I can't verify, if ApplicationPgpKeyUrlHandler::handleClick is being called or not... STEPS TO REPRODUCE 1. Receive an email with an attached PGP key, you don't have yet. 2. Open the mail and scroll down to the "OpenPGP Key" section. 3. Click on "Import key" and wonder why nothing happens at all. OBSERVED RESULT No visible reaction whatsoever, the key does not appear in kleopatra's key list afterwards EXPECTED RESULT Kleopatra opens, importing the key.

I cannot reproduce this. I get the message "The key has been successfully imported" after clicking on "Import key". Even for an encrypted message with attached OpenPGP key I get this message although the actual import fails (see bug 469383). Since your report says that "nothing happens at all", I assume that your problem has been fixed because in the current version the import is at least attempted and the result is reported. If the problem still persists for you with the latest version of KMail (currently 5.23.0 in KDE Gear release 23.04.0), then please run KMail with GpgME debugging like this `GPGME_DEBUG=8 kmail` in Konsole.
