Hello everyone!

When sending an email to myself, which is signed with my GPG key, I get the following error:

"Message was signed by MYEMAILHERE (Key ID: 0x79E52FAB08F75808).
The signature is valid, but the key's validity is unknown."

It worked flawlessly on my deceased notebook, but I get this error message on my new desktop installation. What could be the reason?

I have:
KDE Frameworks 5.35.0
Qt 5.9.0 (built against 5.9.0)
Kmail / Kgpg 17.04.2-1

Thanks!

Kgpg bug is worked on. Meanwhile one can set the trust level is in Kleopatra, resolving this issue.
