twisted.mail.smtp.SMTPClient : API documentation

SMTP client for sending emails.

After the client has connected to the SMTP server, it repeatedly calls SMTPClient.getMailFrom, SMTPClient.getMailTo and SMTPClient.getMailData and uses this information to send an email. It then calls SMTPClient.getMailFrom again; if it returns None, the client will disconnect, otherwise it will continue as normal i.e. call SMTPClient.getMailTo and SMTPClient.getMailData and send a new email.

Method	__init__	Undocumented
Method	sendLine	Sends a line to the other end of the connection.
Method	connectionMade	Called when a connection is made.
Method	connectionLost	We are no longer connected
Method	timeoutConnection	Called when the connection times out.
Method	lineReceived	Override this for when each line is received.
Method	smtpConnectionFailed	Undocumented
Method	smtpTransferFailed	Undocumented
Method	smtpState_helo	Undocumented
Method	smtpState_from	Undocumented
Method	smtpState_disconnect	Undocumented
Method	smtpState_to	Undocumented
Method	smtpState_toOrData	Undocumented
Method	smtpState_data	Undocumented
Method	smtpState_msgSent	Undocumented
Method	transformChunk	Perform the necessary local to network newline conversion and escape leading periods.
Method	finishedFileTransfer	Undocumented
Method	getMailFrom	Return the email address the mail is from.
Method	getMailTo	Return a list of emails to send to.
Method	getMailData	Return file-like object containing data of message to be sent.
Method	sendError	If an error occurs before a mail message is sent sendError will be called. This base class method sends a QUIT if the error is non-fatal and disconnects the connection.
Method	sentMail	Called when an attempt to send an email is completed.
Method	_disconnectFromServer	Undocumented

Inherited from LineReceiver:

Class Variable	delimiter	The line-ending delimiter to use. By default this is `b'\r\n'`.
Class Variable	MAX_LENGTH	The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.
Method	clearLineBuffer	Clear buffered data.
Method	dataReceived	Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.)
Method	setLineMode	Sets the line-mode of this receiver.
Method	setRawMode	Sets the raw mode of this receiver. Further data received will be sent to rawDataReceived rather than lineReceived.
Method	rawDataReceived	Override this for when raw data is received.
Method	lineLengthExceeded	Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.

Inherited from Protocol (via LineReceiver):

Method

logPrefix

Return a prefix matching the class name, to identify log messages related to this protocol instance.

Inherited from BaseProtocol (via LineReceiver, Protocol):

Method

makeConnection

Make a connection to a transport and a server.

Inherited from _PauseableMixin (via LineReceiver):

Method	pauseProducing	Undocumented
Method	resumeProducing	Undocumented
Method	stopProducing	Undocumented

Inherited from TimeoutMixin:

Class Variable	timeOut	The number of seconds after which to timeout the connection.
Method	callLater	Wrapper around `reactor.callLater` for test purpose.
Method	resetTimeout	Reset the timeout count down.
Method	setTimeout	Change the timeout period
Method	__timedOut	Undocumented

Sends a line to the other end of the connection.

Parameters line The line to send, not including the delimiter. (type: bytes)

Called when a connection is made.

This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here.

We are no longer connected

Called when the connection times out.

Override to define behavior other than dropping the connection.

Override this for when each line is received.

Parameters line The line which was received with the delimiter removed. (type: bytes)

Perform the necessary local to network newline conversion and escape leading periods.

This method also resets the idle timeout so that as long as process is being made sending the message body, the client will not time out.

Return the email address the mail is from.

Return a list of emails to send to.

Return file-like object containing data of message to be sent.

Lines in the file should be delimited by '\n'.

If an error occurs before a mail message is sent sendError will be called. This base class method sends a QUIT if the error is non-fatal and disconnects the connection.

Parameters exc The SMTPClientError (or child class) raised (type: SMTPClientError)

Called when an attempt to send an email is completed.

If some addresses were accepted, code and resp are the response to the DATA command. If no addresses were accepted, code is -1 and resp is an informative message.

Parameters	code	the code returned by the SMTP Server
	resp	The string response returned from the SMTP Server
	numOK	the number of addresses accepted by the remote host.
	addresses	is a list of tuples (address, code, resp) listing the response to each RCPT command.
	log	is the SMTP session log
