describe Mail::BccField do
  
  #    The "Bcc:" field (where the "Bcc" means "Blind Carbon Copy") contains
  #    addresses of recipients of the message whose addresses are not to be
  #    revealed to other recipients of the message.  There are three ways in
  #    which the "Bcc:" field is used.  In the first case, when a message
  #    containing a "Bcc:" field is prepared to be sent, the "Bcc:" line is
  #    removed even though all of the recipients (including those specified
  #    in the "Bcc:" field) are sent a copy of the message.  In the second
  #    case, recipients specified in the "To:" and "Cc:" lines each are sent
  #    a copy of the message with the "Bcc:" line removed as above, but the
  #    recipients on the "Bcc:" line get a separate copy of the message
  #    containing a "Bcc:" line.  (When there are multiple recipient
  #    addresses in the "Bcc:" field, some implementations actually send a
  #    separate copy of the message to each recipient with a "Bcc:"
  #    containing only the address of that particular recipient.) Finally,
  #    since a "Bcc:" field may contain no addresses, a "Bcc:" field can be
  #    sent without any addresses indicating to the recipients that blind
  #    copies were sent to someone.  Which method to use with "Bcc:" fields
  #    is implementation dependent, but refer to the "Security
  #    Considerations" section of this document for a discussion of each.
