--------------
|
|
|
|
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 string 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, and sources and binaries for servers
|
|
implementing it, can all be found at the University of Washington's *IMAP
|
|
Information Center* (https://www.washington.edu/imap/).

|
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 string, 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.
|

|
|
phrase ``AUTH=CRAM-MD5``.
|
|
|
|
|
|
.. method:: IMAP4.logout()
|

|
|
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

The *timeout* parameter was added.
|
|
|
|
.. method:: IMAP4.partial(message_num, message_part, start, length)

|
|
|
|
|
|
.. method:: IMAP4.recent()
|
|
|
|

|
|
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.
|
|
|
|
.. audit-event:: imaplib.send self,data imaplib.IMAP4.send
|
|
|
|
|
|
.. method:: IMAP4.setacl(mailbox, who, what)
|
|
|
|
Set an ``ACL`` for *mailbox*. The method is non-standard, but is supported by
|
|
the ``Cyrus`` server.
|
|
|
|
|
|
.. method:: IMAP4.setannotation(mailbox, entry, attribute[, ...])
|
|
|
|
Set ``ANNOTATION``\ s for *mailbox*. The method is non-standard, but is
|
|
supported by the ``Cyrus`` server.
|
|
|
|
|
|
.. method:: IMAP4.setquota(root, limits)
|
|
|
|
Set the ``quota`` *root*'s resource *limits*. This method is part of the IMAP4
|
|
QUOTA extension defined in rfc2087.
|
|
|
|
|
|
.. 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.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()
