      * Forge email headers
      * -------------------
      *
      * WARNING
      *
      * DO NOT add To: or Subject: headers at this step. They need to be
      * handled differently depending upon the mailer we are going to use.
      *
      * To:
      *  PHP mail() first argument is the mail receiver. The argument is
      *  used as a recipient destination and as a To header.
      *
      *  PEAR mailer has a recipient argument which is only used to
      *  send the mail. If no To header is given, PEAR will set it to
      *  to 'undisclosed-recipients:'.
      *
      *  NOTE: To: is for presentation, the actual recipient is specified
      *  by the mailer using the Rcpt-To: header.
      *
      * Subject:
      *  PHP mail() second argument to pass the subject, passing a Subject
      *  as an additional header will result in a duplicate header.
      *
      *  PEAR mailer should be passed a Subject header.
