[Pkg-mutt-maintainers] Bug#840850: mutt: Mutt can't find S/MIME key to sign messages

[Kevin J. McCarthy]

Debian changed the default to use GPGME for GPG and S/MIME encryption.

Please try putting "unset crypt_use_gpgme" in your .muttrc and restart
mutt.  (You must restart mutt for this option to have any effect).
