r�q�XndS(!scAn RFC 2821 smtp proxy.

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.

    --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.

t�dS(sIOverride this abstract method to handle messages from the client.

        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.

        This function should return None, for a normal `250 Ok' response;
        otherwise it returns the desired response string in RFC 821 format.
