Detecting signed/encrypted mail messages
 

I'm searching for a way to detect if the mail is signed/encrypted.

The only idea i have is to search for multipart/signed and
multipart/encrypted content type, but MAPI doesn't seem to implement
content-type.

Detecting signed/encrypted mail messages
 

You will need to search for the MessageClass property (PR_MESSAGE_CLASS in
Extended MAPI) being "IPM.Note.SMIME.MultipartSigned" or "IPM.Note.SMIME".
