Add options to SMIME.Sign
- Do not detach signature from signed data
By default the signature of a signed message will be sent in a separate MIME entity. This allows non SMIME supported clients to still read the message although they can not verify the signature. Setting this option encodes the complete SMIME message into one MIME entity so that only SMIME supported clients can open the message.
- Do not send the sender's certificate
With this option the message will be a little smaller, but the recipients won't be able to use my certificate to encrypt a reply.
