 | |
| 
 | |
| --------------
 | |
| 
 | |
| This module defines three classes, :class:`IMAP4`, :class:`IMAP4_SSL` and
 | |
| :class:`IMAP4_stream`, which encapsulate a connection to an IMAP4 server and
 | |
| implement a large subset of the IMAP4rev1 client protocol as defined in
 | |
| :rfc:`2060`. It is backward compatible with IMAP4 (:rfc:`1730`) servers, but
 | |
| note that the ``STATUS`` command is not supported in IMAP4.
 | |
| 
 | |
| Three classes are provided by the :mod:`imaplib` module, :class:`IMAP4` is the
 | |
| base class:
 | |
| 
 | |
| 
 | |
| .. class:: IMAP4(host='', port=IMAP4_PORT, timeout=None)
 | |
| 
 | |
|    This class implements the actual IMAP4 protocol.  The connection is created and
 | |
|    protocol version (IMAP4 or IMAP4rev1) is determined when the instance is
 | |
|    initialized. If *host* is not specified, ``''`` (the local host) is used. If
 | |
|    *port* is omitted, the standard IMAP4 port (143) is used. The optional *timeout*
 | |
|    parameter specifies a timeout in seconds for the connection attempt.
 | |
|    If timeout is not given or is None, the global default socket timeout is used.
 | |
| 
 | |
|    The :class:`IMAP4` class supports the :keyword:`with` statement.  When used
 | |
|    like this, the IMAP4 ``LOGOUT`` command is issued automatically when the
 | |
|    :keyword:`!with` statement exits.  E.g.::
 | |
| 
 | |
|     >>> from imaplib import IMAP4
 | |
|     >>> with IMAP4("domain.org") as M:
 | |
|     ...     M.noop()
 | |
|     ...
 | |
|     ('OK', [b'Nothing Accomplished. d25if65hy903weo.87'])
 | |
| 
 | |
|    .. versionchanged:: 3.5
 | |
|       Support for the :keyword:`with` statement was added.
 | |
| 
 | |
|    .. versionchanged:: 3.9
 | |
|       The optional *timeout* parameter was added.
 | |
| 
 | |
| Three exceptions are defined as attributes of the :class:`IMAP4` class:
 | |
| 
 | |
| 
 | |
| .. exception:: IMAP4.error
 | |
| 
 | |
|    Exception raised on any errors.  The reason for the exception is passed to the
 | |
|    constructor as a string.
 | |
| 
 | |
| 
 | |
| .. exception:: IMAP4.abort
 | |
| 
 | |
|    IMAP4 server errors cause this exception to be raised.  This is a sub-class of
 | |
|    :exc:`IMAP4.error`.  Note that closing the instance and instantiating a new one
 | |
|    will usually allow recovery from this exception.
 | |
| 
 | |
| 
 | |
| .. exception:: IMAP4.readonly
 | |
| 
 | |
|    This exception is raised when a writable mailbox has its status changed by the
 | |
|    server.  This is a sub-class of :exc:`IMAP4.error`.  Some other client now has
 | |
|    write permission, and the mailbox will need to be re-opened to re-obtain write
 | |
|    permission.
 | |
| 
 | |
| 
 | |
| There's also a subclass for secure connections:
 | |
| 
 | |
| 
 | |
| .. class:: IMAP4_SSL(host='', port=IMAP4_SSL_PORT, keyfile=None, \
 | |
|                      certfile=None, ssl_context=None, timeout=None)
 | |
| 
 | |
|    This is a subclass derived from :class:`IMAP4` that connects over an SSL
 | |
|    encrypted socket (to use this class you need a socket module that was compiled
 | |
|    with SSL support).  If *host* is not specified, ``''`` (the local host) is used.
 | |
|    If *port* is omitted, the standard IMAP4-over-SSL port (993) is used.
 | |
|    *ssl_context* is a :class:`ssl.SSLContext` object which allows bundling
 | |
|    SSL configuration options, certificates and private keys into a single
 | |
|    (potentially long-lived) structure.  Please read :ref:`ssl-security` for
 | |
|    best practices.
 | |
| 
 | |
|    *keyfile* and *certfile* are a legacy alternative to *ssl_context* - they
 | |
|    can point to PEM-formatted private key and certificate chain files for
 | |
|    the SSL connection.  Note that the *keyfile*/*certfile* parameters are
 | |
|    mutually exclusive with *ssl_context*, a :class:`ValueError` is raised
 | |
|    if *keyfile*/*certfile* is provided along with *ssl_context*.
 | |
| 
 | |
|    The optional *timeout* parameter specifies a timeout in seconds for the
 | |
|    connection attempt. If timeout is not given or is None, the global default
 | |
|    socket timeout is used.
 | |
| 
 | |
|    .. versionchanged:: 3.3
 | |
|       *ssl_context* parameter was added.
 | |
| 
 | |
|    .. versionchanged:: 3.4
 | |
|       The class now supports hostname check with
 | |
|       :attr:`ssl.SSLContext.check_hostname` and *Server Name Indication* (see
 | |
|       :data:`ssl.HAS_SNI`).
 | |
| 
 | |
|    .. deprecated:: 3.6
 | |
| 
 | |
|        *keyfile* and *certfile* are deprecated in favor of *ssl_context*.
 | |
|        Please use :meth:`ssl.SSLContext.load_cert_chain` instead, or let
 | |
|        :func:`ssl.create_default_context` select the system's trusted CA
 | |
|        certificates for you.
 | |
| 
 | |
|    .. versionchanged:: 3.9
 | |
|       The optional *timeout* parameter was added.
 | |
| 
 | |
| The second subclass allows for connections created by a child process:
 | |
| 
 | |
| 
 | |
| .. class:: IMAP4_stream(command)
 | |
| 
 | |
|    This is a subclass derived from :class:`IMAP4` that connects to the
 | |
|    ``stdin/stdout`` file descriptors created by passing *command* to
 | |
|    ``subprocess.Popen()``.
 | |
| 
 | |
| 
 | |
| The following utility functions are defined:
 | |
| 
 | |
| 
 | |
| .. function:: Internaldate2tuple(datestr)
 | |
| 
 | |
|    Parse an IMAP4 ``INTERNALDATE`` string and return corresponding local
 | |
|    time.  The return value is a :class:`time.struct_time` tuple or
 | |
|    ``None`` if the string has wrong format.
 | |
| 
 | |
| .. function:: Int2AP(num)
 | |
| 
 | |
|    Converts an integer into a bytes representation using characters from the set
 | |
|    [``A`` .. ``P``].
 | |
| 
 | |
| 
 | |
| .. function:: ParseFlags(flagstr)
 | |
| 
 | |
|    Converts an IMAP4 ``FLAGS`` response to a tuple of individual flags.
 | |
| 
 | |
| 
 | |
| .. function:: Time2Internaldate(date_time)
 | |
| 
 | |
|    Convert *date_time* to an IMAP4 ``INTERNALDATE`` representation.
 | |
|    The return value is a string in the form: ``"DD-Mmm-YYYY HH:MM:SS
 | |
|    +HHMM"`` (including double-quotes).  The *date_time* argument can
 | |
|    be a number (int or float) representing seconds since epoch (as
 | |
|    returned by :func:`time.time`), a 9-tuple representing local time
 | |
|    an instance of :class:`time.struct_time` (as returned by
 | |
|    :func:`time.localtime`), an aware instance of
 | |
|    :class:`datetime.datetime`, or a double-quoted string.  In the last
 | |
|    case, it is assumed to already be in the correct format.
 | |
| 
 | |
| Note that IMAP4 message numbers change as the mailbox changes; in particular,
 | |
| after an ``EXPUNGE`` command performs deletions the remaining messages are
 | |
| renumbered. So it is highly advisable to use UIDs instead, with the UID command.
 | |
| 
 | |
| At the end of the module, there is a test section that contains a more extensive
 | |
| example of usage.
 | |
| 
 | |
| 
 | |
| .. seealso::

| 
 | |
|    Documents describing the protocol, sources for servers
 | |
|    implementing it, by the University of Washington's IMAP Information Center

 | |
| .. _imap4-objects:
 | |
| 
 | |
| IMAP4 Objects
 | |
| -------------
 | |
| 
 | |
| All IMAP4rev1 commands are represented by methods of the same name, either
 | |
| upper-case or lower-case.
 | |
| 
 | |
| All arguments to commands are converted to strings, except for ``AUTHENTICATE``,
 | |
| and the last argument to ``APPEND`` which is passed as an IMAP4 literal.  If
 | |
| necessary (the string contains IMAP4 protocol-sensitive characters and isn't
 | |
| enclosed with either parentheses or double quotes) each string is quoted.
 | |
| However, the *password* argument to the ``LOGIN`` command is always quoted. If
 | |
| you want to avoid having an argument string quoted (eg: the *flags* argument to
 | |
| ``STORE``) then enclose the string in parentheses (eg: ``r'(\Deleted)'``).
 | |
| 
 | |
| Each command returns a tuple: ``(type, [data, ...])`` where *type* is usually
 | |
| ``'OK'`` or ``'NO'``, and *data* is either the text from the command response,
 | |
| or mandated results from the command. Each *data* is either a ``bytes``, or a
 | |
| tuple. If a tuple, then the first part is the header of the response, and the
 | |
| second part contains the data (ie: 'literal' value).
 | |
| 
 | |
| The *message_set* options to commands below is a string specifying one or more
 | |
| messages to be acted upon.  It may be a simple message number (``'1'``), a range
 | |
| of message numbers (``'2:4'``), or a group of non-contiguous ranges separated by
 | |
| commas (``'1:3,6:9'``).  A range can contain an asterisk to indicate an infinite
 | |
| upper bound (``'3:*'``).
 | |
| 
 | |
| An :class:`IMAP4` instance has the following methods:
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.append(mailbox, flags, date_time, message)
 | |
| 
 | |
|    Append *message* to named mailbox.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.authenticate(mechanism, authobject)
 | |
| 
 | |
|    Authenticate command --- requires response processing.
 | |
| 
 | |
|    *mechanism* specifies which authentication mechanism is to be used - it should
 | |
|    appear in the instance variable ``capabilities`` in the form ``AUTH=mechanism``.
 | |
| 
 | |
|    *authobject* must be a callable object::
 | |
| 
 | |
|       data = authobject(response)
 | |
| 
 | |
|    It will be called to process server continuation responses; the *response*
 | |
|    argument it is passed will be ``bytes``.  It should return ``bytes`` *data*
 | |
|    that will be base64 encoded and sent to the server.  It should return
 | |
|    ``None`` if the client abort response ``*`` should be sent instead.
 | |
| 
 | |
|    .. versionchanged:: 3.5
 | |
|       string usernames and passwords are now encoded to ``utf-8`` instead of
 | |
|       being limited to ASCII.
 | |
| 
 | |
| 
 | |

 | |
| 
 | |
|    Checkpoint mailbox on server.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.close()

 | |
|    (see :RFC:`6855`).
 | |
| 
 | |
|    .. versionadded:: 3.5

 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.expunge()
 | |
| 
 | |

 | |
|    response for each deleted message. Returned data contains a list of ``EXPUNGE``
 | |
|    message numbers in order received.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.fetch(message_set, message_parts)
 | |
| 
 | |
|    Fetch (parts of) messages.  *message_parts* should be a string of message part
 | |
|    names enclosed within parentheses, eg: ``"(UID BODY[TEXT])"``.  Returned data
 | |
|    are tuples of message part envelope and data.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.getacl(mailbox)

 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.list([directory[, pattern]])
 | |
| 
 | |
|    List mailbox names in *directory* matching *pattern*.  *directory* defaults to
 | |
|    the top-level mail folder, and *pattern* defaults to match anything.  Returned
 | |
|    data contains a list of ``LIST`` responses.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.login(user, password)
 | |
| 
 | |
|    Identify the client using a plaintext password. The *password* will be quoted.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.login_cram_md5(user, password)
 | |
| 
 | |
|    Force use of ``CRAM-MD5`` authentication when identifying the client to protect
 | |
|    the password.  Will only work if the server ``CAPABILITY`` response includes the

 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.logout()
 | |
| 
 | |
|    Shutdown connection to server. Returns server ``BYE`` response.

 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.namespace()
 | |
| 
 | |
|    Returns IMAP namespaces as defined in :rfc:`2342`.

| 
 | |
| 
 | |
| .. method:: IMAP4.open(host, port, timeout=None)
 | |
| 
 | |
|    Opens socket to *port* at *host*. The optional *timeout* parameter
 | |
|    specifies a timeout in seconds for the connection attempt.
 | |
|    If timeout is not given or is None, the global default socket timeout
 | |
|    is used. Also note that if the *timeout* parameter is set to be zero,
 | |
|    it will raise a :class:`ValueError` to reject creating a non-blocking socket.
 | |
|    This method is implicitly called by the :class:`IMAP4` constructor.
 | |
|    The connection objects established by this method will be used in
 | |
|    the :meth:`IMAP4.read`, :meth:`IMAP4.readline`, :meth:`IMAP4.send`,
 | |
|    and :meth:`IMAP4.shutdown` methods. You may override this method.
 | |
| 
 | |
|    .. audit-event:: imaplib.open self,host,port imaplib.IMAP4.open
 | |
| 
 | |
|    .. versionchanged:: 3.9

| 
 | |
|    Fetch truncated part of a message. Returned data is a tuple of message part
 | |
|    envelope and data.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.proxyauth(user)
 | |
| 
 | |
|    Assume authentication as *user*. Allows an authorised administrator to proxy
 | |
|    into any user's mailbox.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.read(size)
 | |
|

 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.readline()
 | |
| 
 | |
|    Reads one line from the remote server. You may override this method.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.recent()
 | |
| 
 | |
|    Prompt server for an update. Returned data is ``None`` if no new messages, else
 | |
|    value of ``RECENT`` response.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.rename(oldmailbox, newmailbox)
 | |
| 
 | |
|    Rename mailbox named *oldmailbox* to *newmailbox*.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.response(code)
 | |
| 
 | |
|    Return data for response *code* if received, or ``None``. Returns the given
 | |
|    code, instead of the usual type.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.search(charset, criterion[, ...])
 | |
| 
 | |
|    Search mailbox for matching messages.  *charset* may be ``None``, in which case
 | |
|    no ``CHARSET`` will be specified in the request to the server.  The IMAP
 | |
|    protocol requires that at least one criterion be specified; an exception will be
 | |
|    raised when the server returns an error.  *charset* must be ``None`` if
 | |
|    the ``UTF8=ACCEPT`` capability was enabled using the :meth:`enable`
 | |
|    command.
 | |
| 
 | |
|    Example::
 | |
| 
 | |
|       # M is a connected IMAP4 instance...
 | |
|       typ, msgnums = M.search(None, 'FROM', '"LDJ"')
 | |
| 
 | |
|       # or:
 | |
|       typ, msgnums = M.search(None, '(FROM "LDJ")')
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.select(mailbox='INBOX', readonly=False)
 | |
| 
 | |
|    Select a mailbox. Returned data is the count of messages in *mailbox*
 | |
|    (``EXISTS`` response).  The default *mailbox* is ``'INBOX'``.  If the *readonly*
 | |
|    flag is set, modifications to the mailbox are not allowed.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.send(data)
 | |
| 
 | |
|    Sends ``data`` to the remote server. You may override this method.

 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.shutdown()
 | |
| 
 | |
|    Close connection established in ``open``.  This method is implicitly
 | |
|    called by :meth:`IMAP4.logout`.  You may override this method.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.socket()
 | |
| 
 | |
|    Returns socket instance used to connect to server.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.sort(sort_criteria, charset, search_criterion[, ...])
 | |
| 
 | |
|    The ``sort`` command is a variant of ``search`` with sorting semantics for the
 | |
|    results.  Returned data contains a space separated list of matching message
 | |
|    numbers.
 | |
| 
 | |
|    Sort has two arguments before the *search_criterion* argument(s); a
 | |
|    parenthesized list of *sort_criteria*, and the searching *charset*.  Note that
 | |
|    unlike ``search``, the searching *charset* argument is mandatory.  There is also
 | |
|    a ``uid sort`` command which corresponds to ``sort`` the way that ``uid search``
 | |
|    corresponds to ``search``.  The ``sort`` command first searches the mailbox for
 | |
|    messages that match the given searching criteria using the charset argument for
 | |
|    the interpretation of strings in the searching criteria.  It then returns the
 | |
|    numbers of matching messages.
 | |
| 
 | |
|    This is an ``IMAP4rev1`` extension command.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.starttls(ssl_context=None)
 | |
| 
 | |
|    Send a ``STARTTLS`` command.  The *ssl_context* argument is optional
 | |
|    and should be a :class:`ssl.SSLContext` object.  This will enable
 | |
|    encryption on the IMAP connection.  Please read :ref:`ssl-security` for
 | |
|    best practices.

| 
 | |
|    .. versionadded:: 3.2
 | |
| 
 | |
|    .. versionchanged:: 3.4
 | |
|       The method now supports hostname check with
 | |
|       :attr:`ssl.SSLContext.check_hostname` and *Server Name Indication* (see
 | |
|       :data:`ssl.HAS_SNI`).
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.status(mailbox, names)
 | |
| 
 | |
|    Request named status conditions for *mailbox*.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.store(message_set, command, flag_list)
 | |
| 
 | |
|    Alters flag dispositions for messages in mailbox.  *command* is specified by
 | |
|    section 6.4.6 of :rfc:`2060` as being one of "FLAGS", "+FLAGS", or "-FLAGS",
 | |
|    optionally with a suffix of ".SILENT".
 | |
| 
 | |
|    For example, to set the delete flag on all messages::
 | |
| 
 | |
|       typ, data = M.search(None, 'ALL')
 | |
|       for num in data[0].split():
 | |
|          M.store(num, '+FLAGS', '\\Deleted')
 | |
|       M.expunge()
 | |
| 
 | |
|    .. note::
 | |
| 
 | |
|       Creating flags containing ']' (for example: "[test]") violates
 | |
|       :rfc:`3501` (the IMAP protocol).  However, imaplib has historically
 | |
|       allowed creation of such tags, and popular IMAP servers, such as Gmail,
 | |
|       accept and produce such flags.  There are non-Python programs which also
 | |
|       create such tags.  Although it is an RFC violation and IMAP clients and
 | |
|       servers are supposed to be strict, imaplib nonetheless continues to allow
 | |
|       such tags to be created for backward compatibility reasons, and as of
 | |
|       Python 3.6, handles them if they are sent from the server, since this
 | |
|       improves real-world compatibility.
 | |
| 
 | |
| .. method:: IMAP4.subscribe(mailbox)
 | |
| 
 | |
|    Subscribe to new mailbox.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.thread(threading_algorithm, charset, search_criterion[, ...])
 | |
| 
 | |
|    The ``thread`` command is a variant of ``search`` with threading semantics for
 | |
|    the results.  Returned data contains a space separated list of thread members.
 | |
| 
 | |
|    Thread members consist of zero or more messages numbers, delimited by spaces,
 | |
|    indicating successive parent and child.
 | |
| 
 | |
|    Thread has two arguments before the *search_criterion* argument(s); a
 | |
|    *threading_algorithm*, and the searching *charset*.  Note that unlike
 | |
|    ``search``, the searching *charset* argument is mandatory.  There is also a
 | |
|    ``uid thread`` command which corresponds to ``thread`` the way that ``uid
 | |
|    search`` corresponds to ``search``.  The ``thread`` command first searches the
 | |
|    mailbox for messages that match the given searching criteria using the charset
 | |
|    argument for the interpretation of strings in the searching criteria. It then
 | |
|    returns the matching messages threaded according to the specified threading
 | |
|    algorithm.
 | |
| 
 | |
|    This is an ``IMAP4rev1`` extension command.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.uid(command, arg[, ...])
 | |
| 
 | |
|    Execute command args with messages identified by UID, rather than message
 | |
|    number.  Returns response appropriate to command.  At least one argument must be
 | |
|    supplied; if none are provided, the server will return an error and an exception
 | |
|    will be raised.
 | |
| 
 | |
| 
 | |
| .. method:: IMAP4.unsubscribe(mailbox)
 | |
| 
 | |
|    Unsubscribe from old mailbox.
 | |
| 
 | |
| .. method:: IMAP4.unselect()
 | |
| 
 | |
|    :meth:`imaplib.IMAP4.unselect` frees server's resources associated with the
 | |
|    selected mailbox and returns the server to the authenticated
 | |
|    state. This command performs the same actions as :meth:`imaplib.IMAP4.close`, except
 | |
|    that no messages are permanently removed from the currently
 | |
|    selected mailbox.
 | |
| 
 | |
|    .. versionadded:: 3.9
 | |
| 
 | |
| .. method:: IMAP4.xatom(name[, ...])
 | |
| 
 | |
|    Allow simple extension commands notified by server in ``CAPABILITY`` response.
 | |
| 
 | |
| 
 | |
| The following attributes are defined on instances of :class:`IMAP4`:
 | |
| 
 | |
| .. attribute:: IMAP4.PROTOCOL_VERSION
 | |
| 
 | |
|    The most recent supported protocol in the ``CAPABILITY`` response from the
 | |
|    server.
 | |
| 
 | |
| 
 | |
| .. attribute:: IMAP4.debug
 | |
| 
 | |
|    Integer value to control debugging output.  The initialize value is taken from
 | |
|    the module variable ``Debug``.  Values greater than three trace each command.
 | |
| 
 | |
| 
 | |
| .. attribute:: IMAP4.utf8_enabled
 | |
| 
 | |
|    Boolean value that is normally ``False``, but is set to ``True`` if an
 | |
|    :meth:`enable` command is successfully issued for the ``UTF8=ACCEPT``
 | |
|    capability.

| IMAP4 Example
 | |
| -------------
 | |
| 
 | |
| Here is a minimal example (without error checking) that opens a mailbox and
 | |
| retrieves and prints all messages::
 | |
| 
 | |
|    import getpass, imaplib
 | |
| 
 | |
|    M = imaplib.IMAP4()
 | |
|    M.login(getpass.getuser(), getpass.getpass())
 | |
|    M.select()
 | |
|    typ, data = M.search(None, 'ALL')
 | |
|    for num in data[0].split():
 | |
|        typ, data = M.fetch(num, '(RFC822)')
 | |
|        print('Message %s\n%s\n' % (num, data[0][1]))
 | |
|    M.close()
 | |
|    M.logout()
