I had s/mime working some times ago. After a few upgrades (pacman -Syu) it works but very strange. When I start claws-mail and trying to make new signed letter it fails with message:
Could not queue message for sending: Signature failed: Secret key not found (End of file)
Then I click some encrypted message, claws-mail says "Could not decrypt: No secret key" (I read message in SENT folder and this is right - I have no key for reading this messages - I sent it to other persone and I have no his key). After that I start again new signed letter and it is sending with no problem (with asking passphrase and signing and then it is signed on the recipient side).
I have gpg-agent and I did all by the howto http://www.claws-mail.org/faq/index.php/S/MIME_howto. Running claws-mail --debug did not say anything usefull.
What can be the reason of this issue ?
I use s/mime very seldome
