Hey there,

I use KMail-4.9.5 and experience a problem with sending pgp-signed e-mail. I use 3 e-mail-addresses (A, B and C) and sign every single outgoing e-mail. The problem can be described as following:

A to A -> valid signature
A to B -> valid signature
A to C -> invalid signature
B to A -> valid signature
B to B -> valid signature
B to C -> valid signature
C to A -> valid signature
C to B -> valid signature
C to C -> valid signature

In the "Sent"-folder, every single e-mail shows a valid signature. I also tested everything with Thunderbird and found out, that this problem only occurs while using KMail and sending an e-mail from A to C. I do not know where to start to look for the reason for this behaviour, so any help would be really appreciated.

Best regards,
Jimini
