Modify framebuffer and NGA framebuffer to read screen size from board model dtb file. Optimise memory usuage of frame buffer Add example minigui application with hooks to profiler (which writes results to S:\). Modified NGA framebuffer to run its own dfc queue at high priority

:mod:`smtpd` --- SMTP Server
============================

.. module:: smtpd
   :synopsis: A SMTP server implementation in Python.

.. moduleauthor:: Barry Warsaw <barry@zope.com>
.. sectionauthor:: Moshe Zadka <moshez@moshez.org>




This module offers several classes to implement SMTP servers.  One is a generic
do-nothing implementation, which can be overridden, while the other two offer
specific mail-sending strategies.


SMTPServer Objects
------------------


.. class:: SMTPServer(localaddr, remoteaddr)

   Create a new :class:`SMTPServer` object, which binds to local address
   *localaddr*.  It will treat *remoteaddr* as an upstream SMTP relayer.  It
   inherits from :class:`asyncore.dispatcher`, and so will insert itself into
   :mod:`asyncore`'s event loop on instantiation.


   .. method:: process_message(peer, mailfrom, rcpttos, data)

      Raise :exc:`NotImplementedError` exception. Override this in subclasses to
      do something useful with this message. Whatever was passed in the
      constructor as *remoteaddr* will be available as the :attr:`_remoteaddr`
      attribute. *peer* is the remote host's address, *mailfrom* is the envelope
      originator, *rcpttos* are the envelope recipients and *data* is a string
      containing the contents of the e-mail (which should be in :rfc:`2822`
      format).


DebuggingServer Objects
-----------------------


.. class:: DebuggingServer(localaddr, remoteaddr)

   Create a new debugging server.  Arguments are as per :class:`SMTPServer`.
   Messages will be discarded, and printed on stdout.


PureProxy Objects
-----------------


.. class:: PureProxy(localaddr, remoteaddr)

   Create a new pure proxy server. Arguments are as per :class:`SMTPServer`.
   Everything will be relayed to *remoteaddr*.  Note that running this has a good
   chance to make you into an open relay, so please be careful.


MailmanProxy Objects
--------------------


.. class:: MailmanProxy(localaddr, remoteaddr)

   Create a new pure proxy server. Arguments are as per :class:`SMTPServer`.
   Everything will be relayed to *remoteaddr*, unless local mailman configurations
   knows about an address, in which case it will be handled via mailman.  Note that
   running this has a good chance to make you into an open relay, so please be
   careful.
