05/05/2005 - v2.00-rc2 - Brandon Zehm
          - Added ability to mark subject with a spam notice
          - Put DSPAM Signature for each message into the maillog
          - Now all DSPAM headers are included in the .nfo file
          - DSPAM module now syslogs the confidence and probability of each message.
          - Brandon Zehm: Module:dspam - read multiline headers from dspam.
          - Brandon Zehm: Added an "always-process" option to each of the
                          modules. If disabled (default) dspampd will stop
                          processing modules when one module has already
                          decided to not deliver a message.
          - Kurt Keller: Determine hostname differently $HOSTNAME is not
                         universally available in the environment.
          - Kurt Keller: Mention --list in help message.
          - Kurt Keller: Fix problem with removing # comments from config file.
          - Kurt Keller: RFC 2822 does not require whitespace after "Message-ID:".   
          - Kurt Keller: Handle RSET and QUIT commands which are issued before the
                         DATA command.
          - Kurt Keller: SMTP DATA command is now only intercepted if it is
                         likely to succeed (MAIL FROM and RCPT TO have been successful)
          - Kurt Keller: ClamAV can now be used with UNIX domain sockets as well.
          - Kurt Keller: New configuration parameters in the [module:clamav] section:
                         socktype, peeraddr, port, peersocket
          - Kurt Keller: Returning undef from within hear() causes sessions to hang.
                         Return a 441 temporary failure instead to tip off the remote
                         host and cause it to try sending the message again later.
          - Kurt Keller: Only use lower case for dspam-user; dspam would see
                         'Me@my.domain' and 'me@my.domain' differently.
          - Brandon Zehm: Put DSPAM Signature for each message into the maillog
          - Brandon Zehm: Now all DSPAM headers (and a few other things) are included
                          in the .nfo file
          - Brandon Zehm: Small bug with handling output from getline().. it wasn't
                          returning undef on error, so I modified the code
                          that called it to work properly.
          - Brandon Zehm: If no Message-ID is present create one and insert it into the
                          message headers.
          - Brandon Zehm: More changes to handle RSET and QUIT properly.
          - Brandon Zehm: Discard incoming DSPAM headers even when they
                          span multiple lines.
          - Brandon Zehm: If writing ClamAV headers make sure to discard
                          ClamAV headers from the incoming message.

      06/17/2004 - v2.00-rc1 - Brandon Zehm
          - DspamPD is now mostly configured with a configuration file
            rather than 50 command line parameters.
          - The program was resesigned to be much more modular, 
            and has two modules: dspam, and clamav.
          - You can specify custom smtp responses for messages classified as
            ham, spam, clean, infected, etc.
          - DspamPD is designed to run with DSPAM v3.0.0 now, previous 
            versions of dspam will not work without changing the command
            line parameters the dspam command is run with.
          - Too many other changes to list, but the basic functionality 
            remains the same.
