\section{\module{smtpd} --- SMTP Server} \declaremodule{standard}{smtpd} \moduleauthor{Barry Warsaw}{[email protected]} \sectionauthor{Moshe Zadka}{[email protected]} \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}
