"""An RFC 5321 smtp proxy with optional RFC 1870 and RFC 6531 extensions.

Usage: %(program)s [options] [localhost:localport [remotehost:remoteport]]

Options:

--nosetuid
    -n
        This program generally tries to setuid `nobody', unless this flag is
        set.  The setuid call will fail if this program is not run as root (in
        which case, use this flag).

--version
    -V
        Print the version number and exit.

--class classname
    -c classname
        Use `classname' as the concrete SMTP proxy class.  Uses `PureProxy' by
        default.

--size limit
    -s limit
        Restrict the total size of the incoming message to "limit" number of
        bytes via the RFC 1870 SIZE extension.  Defaults to 33554432 bytes.

--smtputf8
    -u
        Enable the SMTPUTF8 extension and behave as an RFC 6531 smtp proxy.

--debug
    -d
        Turn on debugging prints.

--help
    -h
        Print this message and exit.

Version: %(__version__)s

If localhost is not given then `localhost' is used, and if localport is not
given then 8025 is used.  If remotehost is not given then `localhost' is used,
and if remoteport is not given, then 25 is used.

# Overview:
#
# This file implements the minimal SMTP protocol as defined in RFC 5321.  It
# has a hierarchy of classes which implement the backend functionality for the
# smtpd.  A number of classes are provided:
#
#   SMTPServer - the base class for the backend.  Raises NotImplementedError
#   if you try to use it.
#
#   DebuggingServer - simply prints each message it receives on stdout.
#
#   PureProxy - Proxies all messages to a real smtpd which does final
#   delivery.  One known problem with this class is that it doesn't handle
#   SMTP errors from the backend server at all.  This should be fixed
#   (contributions are welcome!).
#
#   MailmanProxy - An experimental hack to work with GNU Mailman
#   <www.list.org>.  Using this server as your real incoming smtpd, your
#   mailhost will automatically recognize and accept mail destined to Mailman
#   lists when those lists are created.  Every message not destined for a list
#   gets forwarded to a real backend smtpd, as with PureProxy.  Again, errors
#   are not handled correctly yet.
#
#
# Author: Barry Warsaw <barry@python.org>
#
# TODO:
#
# - support mailbox delivery
# - alias files
# - Handle more ESMTP extensions
# - handle error codes from the backend smtpd

peer is a tuple containing (ipaddr, port) of the client that made the
        socket connection to our smtp port.

mailfrom is the raw address the client claims the message is coming
        from.

rcpttos is a list of raw addresses the client wishes to deliver the
        message to.

data is a string containing the entire full text of the message,
        headers (if supplied) and all.  It has been `de-transparencied'
        according to RFC 821, Section 4.5.2.  In other words, a line
        containing a `.' followed by other text has had the leading dot
        removed.

kwargs is a dictionary containing additional information.  It is
        empty if decode_data=True was given as init parameter, otherwise
        it will contain the following keys:
            'mail_options': list of parameters to the mail command.  All

                            ['BODY=8BITMIME', 'SMTPUTF8'].
            'rcpt_options': same, for the rcpt command.

This function should return None for a normal `250 Ok' response;
