Log Message:
Here are the most important changes in MIMEDefang 2.73:

* A new -G option causes files created by mimedefang to
  be group-readable and sockets to be group readable/writable.
* The multiplexor snoops in on communications and saves the
  Sendmail queue-ID for logging purposes. It logs the queue ID when
  logging a slave's STDERR.
* MIMEDefang passes along the client port number, server IP address
  and server port number to all filter functions. This feature was
  sponsored by Scayl.
