def __init__(self, contextFactory=None): (source)
Undocumented
def registerAuthenticator(self, auth): (source)

Register a new form of authentication

When invoking the authenticate() method of IMAP4Client, the first matching authentication scheme found will be used. The ordering is that in which the server lists support authentication schemes.

ParametersauthThe object to use to perform the client side of this authentication scheme. (type: Implementor of IClientAuthentication)
def rawDataReceived(self, data): (source)

Override this for when raw data is received.

def _setupForLiteral(self, rest, octets): (source)
Undocumented
def connectionMade(self): (source)

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.

def connectionLost(self, reason): (source)
def lineReceived(self, line): (source)

Attempt to parse a single line from the server.

ParameterslineThe line from the server, without the line delimiter. (type: bytes)
RaisesIllegalServerResponseIf the line or some part of the line does not represent an allowed message from the server at this time.
def timeoutConnection(self): (source)

Called when the connection times out.

Override to define behavior other than dropping the connection.

def _regularDispatch(self, line): (source)

Undocumented
def sendCommand(self, cmd): (source)
Undocumented
def getCapabilities(self, useCache=1): (source)

Request the capabilities available on this server.

ReturnsA deferred whose callback will be invoked with a dictionary mapping capability types to lists of supported mechanisms, or to None if a support list is not applicable. (type: Deferred)
def __cbCapabilities(self, result): (source)

ParameterscontextFactoryThe TLS / SSL Context Factory to leverage. If the contextFactory is None the IMAP4Client will either use the current TLS / SSL Context Factory or attempt to create a new one. (type: ssl.ClientContextFactory)
ReturnsA Deferred which fires when the transport has been secured according to the given contextFactory, or which fails if the transport cannot be secured.
def authenticate(self, secret): (source)

Attempt to enter the authenticated state with the server

Undocumented
def __cbAuthTLS(self, caps, secret): (source)
Undocumented
def login(self, username, password): (source)

Authenticate with the server using a username and password

This command is allowed in the Non-Authenticated state. If the server supports the STARTTLS capability and our transport supports TLS, TLS is negotiated before the login command is issued.

def _parseFetchPairs(self, fetchResponseList): (source)

Given the result of parsing a single FETCH response, construct a dict mapping response keys to response values.

ParametersfetchResponseListThe result of parsing a FETCH response with parseNestedParens and extracting just the response data (that is, just the part that comes after "FETCH"). The form of this input (and therefore the output of this method) is very disagreeable. A valuable improvement would be to enumerate the possible keys (representing them as structured objects of some sort) rather than using strings and tuples of tuples of strings and so forth. This would allow the keys to be documented more easily and would allow for a much simpler application-facing API (one not based on looking up somewhat hard to predict keys in a dict). Since fetchResponseList notionally represents a flattened sequence of pairs (identifying keys followed by their associated values), collapsing such complex elements of this list as ["BODY", ["HEADER.FIELDS", ["SUBJECT"]]] into a single object would also greatly simplify the implementation of this method.
ReturnsA dict of the response data represented by pairs. Keys in this dictionary are things like "RFC822.TEXT", "FLAGS", or ("BODY", ("HEADER.FIELDS", ("SUBJECT",))). Values are entirely dependent on the key with which they are associated, but retain the same structured as produced by parseNestedParens.

headerNumberThe nested rfc822 index specifying the entity to retrieve. For example, 1 retrieves the first entity of the message, and (2, 1, 3) retrieves the 3rd entity inside the first entity inside the second entity of the message. (type: int or int sequence)
