smtpd --- SMTP ServerSource code: Lib/smtpd.py
[UNKNOWN NODE transition]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.
class smtpd.SMTPServer(localaddr, remoteaddr)[source]
Create a new SMTPServer object, which binds to local address
localaddr. It will treat remoteaddr as an upstream SMTP relayer. Both
localaddr and remoteaddr should be a (host, port)
tuple. The object inherits from asyncore.dispatcher, and so will
insert itself into asyncore's event loop on instantiation.
process_message(peer, mailfrom, rcpttos, data)[source]
Raise 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 _remoteaddr
attribute. peer is the remote host's address, mailfrom is the envelope
originator, rcpttos are the envelope recipients and data is a string
containing the contents of the e-mail (which should be in RFC 2822
format).
class smtpd.DebuggingServer(localaddr, remoteaddr)[source]
Create a new debugging server. Arguments are as per SMTPServer.
Messages will be discarded, and printed on stdout.
class smtpd.PureProxy(localaddr, remoteaddr)[source]
Create a new pure proxy server. Arguments are as per 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.
class smtpd.MailmanProxy(localaddr, remoteaddr)[source]
Create a new pure proxy server. Arguments are as per 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.
