\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}
