def __init__(self, contextFactory=None): (source)

Undocumented

def registerAuthenticator(self, auth): (source)

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.

Parameters auth The object to use to perform the client side of this authentication scheme. (type: Implementor of IClientAuthentication)

def rawDataReceived(self, data): (source)

overrides twisted.protocols.basic.LineReceiver.rawDataReceived

Override this for when raw data is received.

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

Undocumented

def connectionMade(self): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.BaseProtocol.connectionMade

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)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.Protocol.connectionLost

We are no longer connected

def lineReceived(self, line): (source)

overrides twisted.protocols.basic.LineReceiver.lineReceived

Attempt to parse a single line from the server.

Parameters	line	The line from the server, without the line delimiter. (type: `bytes`)
Raises	IllegalServerResponse	If the line or some part of the line does not represent an allowed message from the server at this time.

def timeoutConnection(self): (source)

overrides twisted.protocols.policies.TimeoutMixin.timeoutConnection

Called when the connection times out.

Override to define behavior other than dropping the connection.

def _regularDispatch(self, line): (source)

Undocumented

def messageFile(self, octets): (source)

Create a file to which an incoming message may be written.

Parameters	octets	The number of octets which will be written to the file (type: `int`)

def _extraInfo(self, lines): (source)

Undocumented

def sendCommand(self, cmd): (source)

Undocumented

def getCapabilities(self, useCache=1): (source)

Request the capabilities available on this server.

This command is allowed in any state of connection.

Parameters	useCache	Specify whether to use the capability-cache or to re-retrieve the capabilities from the server. Server capabilities should never change, so for normal use, this flag should never be false. (type: `bool`)
Returns	A 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)

Undocumented

def logout(self): (source)

Inform the server that we are done with the connection.

This command is allowed in any state of connection.

Returns A deferred whose callback will be invoked with None when the proper server acknowledgement has been received. (type: Deferred)

def __cbLogout(self, result): (source)

Undocumented

def noop(self): (source)

Perform no operation.

This command is allowed in any state of connection.

Returns A deferred whose callback will be invoked with a list of untagged status updates the server responds with. (type: Deferred)

def __cbNoop(self, result): (source)

Undocumented

def startTLS(self, contextFactory=None): (source)

Initiates a 'STARTTLS' request and negotiates the TLS / SSL Handshake.

Parameters	contextFactory	The 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`)
Returns	A 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

This command is allowed in the Non-Authenticated state.

Returns A deferred whose callback is invoked if the authentication succeeds and whose errback will be invoked otherwise. (type: Deferred)

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.

A more secure way to log in is to use startTLS or authenticate or both.

Parameters	username	The username to log in with (type: `str`)
	password	The password to log in with (type: `str`)
Returns	A deferred whose callback is invoked if login is successful and whose errback is invoked otherwise. (type: `Deferred`)

def _parseFetchPairs(self, fetchResponseList): (source)

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

Parameters	fetchResponseList	The 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.
Returns	A `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`.

def fetchSpecific(self, messages, uid=0, headerType=None, headerNumber=None, headerArgs=None, peek=None, offset=None, length=None): (source)

Retrieve a specific section of one or more messages

Parameters	messages	A message sequence set (type: `MessageSet` or `str`)
	uid	Indicates whether the message sequence set is of message numbers or of unique message IDs. (type: `bool`)
	headerType	If specified, must be one of HEADER, HEADER.FIELDS, HEADER.FIELDS.NOT, MIME, or TEXT, and will determine which part of the message is retrieved. For HEADER.FIELDS and HEADER.FIELDS.NOT, `headerArgs` must be a sequence of header names. For MIME, `headerNumber` must be specified. (type: `str`)
	headerNumber	The 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)
	headerArgs	If `headerType` is HEADER.FIELDS, these are the headers to retrieve. If it is HEADER.FIELDS.NOT, these are the headers to exclude from retrieval. (type: A sequence of `str`)
	peek	If true, cause the server to not set the \Seen flag on this message as a result of this command. (type: `bool`)
	offset	The number of octets at the beginning of the result to skip. (type: `int`)
	length	The number of octets to retrieve. (type: `int`)
Returns	A deferred whose callback is invoked with a mapping of message numbers to retrieved data, or whose errback is invoked if there is an error. (type: `Deferred`)

def _fetch(self, messages, useUID=0, **terms): (source)

Undocumented

def setFlags(self, messages, flags, silent=1, uid=0): (source)

Set the flags for one or more messages.

This command is allowed in the Selected state.

Parameters	messages	A message sequence set (type: `MessageSet` or `str`)
	flags	The flags to set (type: Any iterable of `str`)
	silent	If true, cause the server to suppress its verbose response. (type: `bool`)
	uid	Indicates whether the message sequence set is of message numbers or of unique message IDs. (type: `bool`)
Returns	A deferred whose callback is invoked with a list of the server's responses (`[]` if `silent` is true) or whose errback is invoked if there is an error. (type: `Deferred`)

def addFlags(self, messages, flags, silent=1, uid=0): (source)

Add to the set flags for one or more messages.

This command is allowed in the Selected state.

Parameters	messages	A message sequence set (type: `MessageSet` or `str`)
	flags	The flags to set (type: Any iterable of `str`)
	silent	If true, cause the server to suppress its verbose response. (type: `bool`)
	uid	Indicates whether the message sequence set is of message numbers or of unique message IDs. (type: `bool`)
Returns	A deferred whose callback is invoked with a list of the server's responses (`[]` if `silent` is true) or whose errback is invoked if there is an error. (type: `Deferred`)

def removeFlags(self, messages, flags, silent=1, uid=0): (source)

Remove from the set flags for one or more messages.

This command is allowed in the Selected state.

Parameters	messages	A message sequence set (type: `MessageSet` or `str`)
	flags	The flags to set (type: Any iterable of `str`)
	silent	If true, cause the server to suppress its verbose response. (type: `bool`)
	uid	Indicates whether the message sequence set is of message numbers or of unique message IDs. (type: `bool`)
Returns	A deferred whose callback is invoked with a list of the server's responses (`[]` if `silent` is true) or whose errback is invoked if there is an error. (type: `Deferred`)

def _store(self, messages, cmd, silent, flags, uid): (source)

Undocumented

def copy(self, messages, mailbox, uid): (source)

Copy the specified messages to the specified mailbox.

This command is allowed in the Selected state.

Parameters	messages	A message sequence set (type: `MessageSet` or `str`)
	mailbox	The mailbox to which to copy the messages (type: `str`)
	uid	If true, the `messages` refers to message UIDs, rather than message sequence numbers. (type: `bool`)
Returns	A deferred whose callback is invoked with a true value when the copy is successful, or whose errback is invoked if there is an error. (type: `Deferred`)
