; The mailman object is used for sending and receiving email.

; Tell the mailman to use a PFX file as a source for locating
; the certificate and private key required for signing.
; The certificate chosen for signing will be the one that
; matches the sender's email address, which also has
; a private key.  All intermediate certs in the chain of 
; authentication, up to and including the root, will
; be included in the signature.

; Signed email can be sent in two different ways.  
; In a multipart/signed email, the signature is attached as a separate MIME part.
; In an opaque email (signedData) the content of the email is encapsulated within the signature
; and the email is sent as "application/pkcs7-mime". 
; Either should be fine, but some receiving systems might require one or the other..
