For some reason Kmail is unable to understand signed/encrypted messages from Thunderbird. Here is the error message I get in kmail.

######################
Encrypted message
Message was signed with unknown key.

End of signed message

In Thunderbird I get [Decrypted message; Good signature from...]

So it seems Thunderbird is working fine.

I was testing both kmail and thunderbird by sending my self signed and encrypted email with two email accounts. I wanted to make sure I had everything setup correctly. Both programs will let me "read" the emails. Thunderbird seems to validate my keys just fine. Its when I send my self an email from Thunderbird and read it in Kmail that Kmail doesn't recognize the key even though it's my key on my system.

Now if I send my self an email from kmail and read it in kmail it works just fine.

Do you need to load the key into KMail instead of just having it on your system?

I'm not sure I know what you mean. My keys where made with KGpg, which is just a GUI front end to GnuPG. The keys are stored under ~/.gnupg which is the same place that Thunderbird can read or write keys. From what I can tell it looks like Enigmail (the software in Thunderbird used for handling keys) is formating the headers in the mail in a way that kmail has trouble understanding.

If you give me your GPG public key (if you have one) I can send you a signed and encrypted email from both thunderbird and kmail so you can see the difference in the headers.

I was thinking more along the lines of what you have to do with pkcs keys where you have to load them into each app that is using them.

I'm not sure how to explain it in words so I'll take a screen shot of how both programs interact with GPG.

Hello,

I've the same problem...
Keys are imported and all others staff works fine...
ha.. When mail is only signed there is no problem. The problem is with mails which are signed and encrypted. Then Kmail can't understand gpg headers and in the kmail I can see:
"Encrypted message
Message was signed with unknown key.
The validity of the signature cannot be verified.
Status: Error: Signature not verified Hide Details
No Audit Log available"

Any known solution ?

Best regards
