20.13. smtpd
--- SMTP Server¶
Source code: 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.
20.13.1. Objek SMTPServer¶
-
class
smtpd.
SMTPServer
(localaddr, remoteaddr)¶ 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 fromasyncore.dispatcher
, and so will insert itself intoasyncore
's event loop on instantiation.-
process_message
(peer, mailfrom, rcpttos, data)¶ 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).
-
20.13.2. Objek DebuggingServer¶
-
class
smtpd.
DebuggingServer
(localaddr, remoteaddr)¶ Create a new debugging server. Arguments are as per
SMTPServer
. Messages will be discarded, and printed on stdout.
20.13.3. Objek PureProxy¶
-
class
smtpd.
PureProxy
(localaddr, remoteaddr)¶ 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.
20.13.4. Objek MailmanProxy¶
-
class
smtpd.
MailmanProxy
(localaddr, remoteaddr)¶ 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.
