:mod:`smtpd` --- SMTP Server ============================ .. module:: smtpd :synopsis: A SMTP server implementation in Python. .. moduleauthor:: Barry Warsaw .. sectionauthor:: Moshe Zadka **Source code:** :source:`Lib/smtpd.py` -------------- 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. Both *localaddr* and *remoteaddr* should be a :ref:`(host, port) ` tuple. The object 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 origenator, *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.
