+\modulesynopsis{Implement a flexible SMTP server}
+
+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.
+
+
+\subsection{SMTPServer Objects}
+
+\begin{classdesc}{SMTPServer}{localaddr, remoteaddr}
+Create a new \class{SMTPServer} object, which binds to local address
+\var{localaddr}.  It will treat \var{remoteaddr} as an upstream SMTP
+relayer.  It inherits from \class{asyncore.dispatcher}, and so will
+insert itself into \refmodule{asyncore}'s event loop on instantiation.
+\end{classdesc}
+
+\begin{methoddesc}[SMTPServer]{process_message}{peer, mailfrom, rcpttos, data}
+Raise \exception{NotImplementedError} exception. Override this in
+subclasses to do something useful with this message. Whatever was
+passed in the constructor as \var{remoteaddr} will be available as the
+\member{_remoteaddr} attribute. \var{peer} is the remote host's address,
+\var{mailfrom} is the envelope originator, \var{rcpttos} are the
+envelope recipients and \var{data} is a string containing the contents
+of the e-mail (which should be in \rfc{2822} format).
+\end{methoddesc}
+
+
+\subsection{DebuggingServer Objects}
+
+\begin{classdesc}{DebuggingServer}{localaddr, remoteaddr}
+Create a new debugging server.  Arguments are as per
+\class{SMTPServer}.  Messages will be discarded, and printed on
+stdout.
+\end{classdesc}
+
+
+\subsection{PureProxy Objects}
+
+\begin{classdesc}{PureProxy}{localaddr, remoteaddr}
+Create a new pure proxy server. Arguments are as per \class{SMTPServer}.
+Everything will be relayed to \var{remoteaddr}.  Note that running
+this has a good chance to make you into an open relay, so please be
+careful.
+\end{classdesc}
+
+
+\subsection{MailmanProxy Objects}
+
+\begin{classdesc}{MailmanProxy}{localaddr, remoteaddr}
+Create a new pure proxy server. Arguments are as per
+\class{SMTPServer}.  Everything will be relayed to \var{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.
+\end{classdesc}
