View In Hierarchy

A base class for ESMTP relayers.

Method __init__ No summary

Inherited from RelayerMixin:

Method getMailData Undocumented
Method getMailFrom Undocumented
Method getMailTo Undocumented
Method loadMessages Undocumented
Method sentMail Since we only use one recipient per envelope, this will be called with 0 or 1 addresses. We probably want to do something with the error message if we failed.
Instance Variable messages Undocumented
Instance Variable names Undocumented

Inherited from ESMTPClient (via RelayerMixin):

Method __getattr__ Undocumented
Method __setattr__ Undocumented
Method authenticate Undocumented
Method connectionMade Called when a connection has been made, and triggers sending an EHLO to the server.
Method esmtpAUTHDeclined Fail because the authentication was rejected.
Method esmtpAUTHMalformedChallenge Fail because the server sent a malformed authentication challenge.
Method esmtpAUTHRequired Fail because authentication is required, but the server does not support any schemes we support.
Method esmtpAUTHServerError Fail because of some other authentication error.
Method esmtpEHLORequired Fail because authentication is required, but the server does not support ESMTP, which is required for authentication.
Method esmtpState_challenge Undocumented
Method esmtpState_ehlo Send an EHLO to the server.
Method esmtpState_serverConfig Handle a positive response to the EHLO command by parsing the capabilities in the server's response and then taking the most appropriate next step towards entering a mail transaction.
Method esmtpState_starttls Handle a positive response to the STARTTLS command by starting a new TLS session on self.transport.
Method esmtpTLSFailed Fail because the TLS handshake wasn't able to be completed.
Method esmtpTLSRequired Fail because TLS is required and the server does not support it.
Method registerAuthenticator Registers an Authenticator with the ESMTPClient. The ESMTPClient will attempt to login to the SMTP Server in the order the Authenticators are registered. The most secure Authentication mechanism should be registered first.
Method smtpState_maybeAuthenticated Called to handle the next message from the server after sending a response to a SASL challenge. The server response might be another challenge or it might indicate authentication has succeeded.
Method tryTLS Take a necessary step towards being able to begin a mail transaction.
Instance Variable authenticators Undocumented
Instance Variable context The context factory to use for STARTTLS, if desired.
Instance Variable heloFallback Whether or not to fall back to plain SMTP if the EHLO command is not recognised by the server. If requireAuthentication is True, or requireTransportSecurity is True and the connection is not over TLS, this fallback flag will not be honored.
Instance Variable requireAuthentication If True, refuse to proceed if authentication cannot be performed. Overrides heloFallback.
Instance Variable requireTransportSecurity If True, refuse to proceed if the transport cannot be secured. If the transport layer is not already secured via TLS, this will override heloFallback.
Instance Variable secret Undocumented
Method _authResponse Undocumented
Method _esmtpState_plainAuth Undocumented
Instance Variable _authinfo Undocumented
Instance Variable _expected Undocumented
Instance Variable _failresponse Undocumented
Instance Variable _okresponse Undocumented
Instance Variable _tlsMode Whether or not the connection is over TLS.

Inherited from SMTPClient (via RelayerMixin, ESMTPClient):

Method connectionLost We are no longer connected
Method finishedFileTransfer Undocumented
Method lineReceived Override this for when each line is received.
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 sendLine Sends a line to the other end of the connection.
Method smtpConnectionFailed Undocumented
Method smtpState_data Undocumented
Method smtpState_disconnect Undocumented
Method smtpState_from Undocumented
Method smtpState_helo Undocumented
Method smtpState_msgSent Undocumented
Method smtpState_to Undocumented
Method smtpState_toOrData Undocumented
Method smtpTransferFailed Undocumented
Method timeoutConnection Called when the connection times out.
Method transformChunk Perform the necessary local to network newline conversion and escape leading periods.
Class Variable debug Undocumented
Class Variable timeout Undocumented
Instance Variable code Undocumented
Instance Variable identity Undocumented
Instance Variable lastAddress Undocumented
Instance Variable log Undocumented
Instance Variable mailFile Undocumented
Instance Variable resp Undocumented
Instance Variable successAddresses Undocumented
Instance Variable toAddresses Undocumented
Instance Variable toAddressesResult Undocumented
Method _disconnectFromServer Undocumented
Instance Variable _from Undocumented

Inherited from LineReceiver (via RelayerMixin, ESMTPClient, SMTPClient):

Method clearLineBuffer Clear buffered data.
Method dataReceived Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.)
Method lineLengthExceeded Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.
Method rawDataReceived Override this for when raw data is received.
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.
Constant 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.
Class Variable delimiter The line-ending delimiter to use. By default this is b'\r\n'.
Instance Variable line_mode Undocumented
Instance Variable _buffer Undocumented
Instance Variable _busyReceiving Undocumented

Inherited from Protocol (via RelayerMixin, ESMTPClient, SMTPClient, LineReceiver):

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.
Class Variable factory Undocumented

Inherited from BaseProtocol (via RelayerMixin, ESMTPClient, SMTPClient, LineReceiver, Protocol):

Method makeConnection Make a connection to a transport and a server.
Instance Variable connected Undocumented
Instance Variable transport Undocumented

Inherited from _PauseableMixin (via RelayerMixin, ESMTPClient, SMTPClient, LineReceiver, Protocol, BaseProtocol):

Method pauseProducing Undocumented
Method resumeProducing Undocumented
Method stopProducing Undocumented
Instance Variable paused Undocumented

Inherited from TimeoutMixin (via RelayerMixin, ESMTPClient, SMTPClient, LineReceiver, Protocol, BaseProtocol, _PauseableMixin):

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