smtpd
— SMTP (简单邮件传输协议) 服务器
¶
源代码： 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.
smtpd.
SMTPServer
(
localaddr
,
remoteaddr
)
¶
创建新的
SMTPServer
对象，绑定到本地地址
localaddr
。它将视
remoteaddr
为上游 SMTP (简单邮件传输协议) 中继器。
localaddr
and
remoteaddr
应该为
(host, port)
元组。对象继承自
asyncore.dispatcher
，且因此将自身插入
asyncore
的实例化事件循环。
process_message
(
peer
,
mailfrom
,
rcpttos
,
data
)
¶
引发
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
属性。
peer
是远程主机的地址，
mailfrom
是信封发起人，
rcpttos
are the envelope recipients and
data
is a string containing the contents of the e-mail (which should be in
RFC 2822
格式)。

DebuggingServer
(
localaddr
,
remoteaddr
)
¶
Create a new debugging server. Arguments are as per
SMTPServer
. Messages will be discarded, and printed on stdout.
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.
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.
