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

' Load the .cer file into a certificate object.
' When sending S/MIME encrypted email, it is the recipient's
' certificate that is used for encryption.  Only the public key
' is needed to encrypt.  The recipient is the only
' one possessing the private key, and therefore is the only
' one able to decrypt.
