Here you can choose which cryptographic message format to use by default with this identity. You can either select any of the four formats supported by KMail or leave the option at the recommended default setting of Any, which will choose a suitable format based on the recipients of the message, or might even go so far as to create two copies of the message, one S/MIME signed and/or encrypted, the other OpenPGP signed and/or encrypted.
