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. --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. � N)�warn)� get_addr_spec�get_angle_addr� SMTPServer�DebuggingServer� PureProxy� MailmanProxyz

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.
