Based on RFC 3501 and original imaplib module.
This is a version of imaplib that uses threads to allow full use of the

Threaded IMAP4rev1 client
Python threaded IMAP4 client module imaplib2
This module defines a class, IMAP4,
which encapsulates a threaded connection to an IMAP4 server
and implements the IMAP4rev1 client protocol
as defined in RFC 3501 with several extensions.
This module presents an almost identical API
as that provided by the standard python library module imaplib,
the main difference being that this version
allows parallel execution of commands on the IMAP4 server,
and implements the IMAP4rev1 IDLE extension.
(imaplib2 can be substituted for imaplib
in existing clients with no changes in the code, but see the caveat below.)
An IMAP4 instance is instantiated with an optional host
and/or port. The defaults are localhost and 143
- the standard IMAP4 port number.
There are also five other optional arguments:
debug=level, debug_file=file, identifier=string, timeout=seconds, debug_buf_lvl=level.
Setting debug level (default: 0) to anything above debug_buf_lvl (default: 3)
causes every action to be printed to file (default: sys.stderr).
Otherwise actions are logged in a circular buffer and the last 20 printed on errors.
The third argument provides a string to be prepended to thread names - useful during debugging (default: target host).
The forth argument sets a timeout for responses from the server, after which the instance will abort.
Note that this timeout is overridden by an IDLE timeout when active.
Caveat: Once an instance has been created,
the invoker must call the logout method before discarding it, to shut down the threads.
There are two classes derived from IMAP4
which provide alternate transport mechanisms:
IMAP4_SSL- IMAP4 client class over an SSL connection.
IMAP4_stream- IMAP4 client class over a stream.
There are also 2 utility methods provided for processing IMAP4 date strings:
Internaldate2Time(datestr)- Converts an IMAP4
INTERNALDATE string to Universal Time.
Returns a time module tuple.
Time2Internaldate(date_time)- Converts
date_time
(a time module tuple,
or an integer or float seconds)
to an IMAP4 INTERNALDATE representation.
Returns a string in the form:
"DD-Mmm-YYYY HH:MM:SS +HHMM"
(including double-quotes).
And there is one utility method for parsing IMAP4 FLAGS responses:
ParseFlags(response)- Convert an IMAP4 flags response
(a string of the form
"...FLAGS (flag ...)")
to a python tuple..
IMAP4 Objects
All IMAP4rev1 commands are represented by methods of the same name
Each command returns a tuple: (type, [data, ...])
where type is usually 'OK' or 'NO',
and data is either the
text from the command response
(always true when type is 'NO'),
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).
Any logical errors raise the exception class
<instance>.error("<reason>").
IMAP4 server errors raise <instance>.abort("<reason>"),
which is a sub-class of error.
Mailbox status changes from READ-WRITE to READ-ONLY
raise <instance>.readonly("<reason>"),
which is a sub-class of abort.
Note that closing the instance and instantiating a new one
will usually recover from an abort.
All commands take two optional named arguments:
callback and cb_arg.
If callback is provided then the command is asynchronous
(the IMAP4 command is scheduled, and the call returns immediately),
and the result will be posted by invoking callback with a single argument:
callback(((type, [data, ...]), cb_arg, None))
or, if there was a problem:
callback((None, cb_arg, (exception class, reason))).
Otherwise the command is synchronous (waits for result). But note
that state-changing commands will both block until previous commands have completed,
and block subsequent commands until they have finished.
All (non-callback) 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 any
non-printing characters or white-space and isn't enclosed with either
parentheses or double quotes or single 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: (\Deleted)).
If you are using sequence sets
containing the wildcard character '*', then enclose the argument
in single quotes: the quotes will be removed and the resulting
string passed unquoted.
To summarise the quoting rules:
- a string is automatically quoted if it contains at least one of the
IMAP4 atom-special characters with the following exceptions:
- the password argument to the
login command is always quoted;
- a string enclosed in
"..." or (...) is passed as is;
- a string enclosed in
'...' is stripped of the enclosing single
quotes and the rest passed as is.
Note also that you can pass in an argument with a type that doesn't evaluate to basestring
(eg: bytearray) and it will be converted to a string without quoting.
There is one instance variable, state, that is useful for tracking
whether the client needs to login to the server. If it has the
value "AUTH" after instantiating the class, then the connection
is pre-authenticated (otherwise it will be "NONAUTH"). Selecting a
mailbox changes the state to be "SELECTED", closing a mailbox changes
back to "AUTH", and once the client has logged out, the state changes
to "LOGOUT" and no further commands may be issued.
There is another instance variable, capabilities,
that holds a list of the capabilities provided by the server (the
same as the list returned by the IMAP4 CAPABILITY command).
An IMAP4 instance has the following methods:
append(mailbox, flags, date_time, message)- Append message to named mailbox.
All args except
message can be None
authenticate(mechanism, authobject)- Authenticate command - requires response processing.
mechanism specifies which authentication mechanism is to
be used - it must appear in <instance>.capabilities in the
form AUTH=mechanism.
authobject must be a callable object:
data = authobject(response)
It will be called to process server continuation responses.
It should return data that will be encoded and sent to the server.
It should return None if the client abort response * should
be sent instead.
capability()- Return server IMAP4 capabilities.
check()- Checkpoint mailbox on server.
close()- Close currently selected mailbox.
Deleted messages are removed from writable mailbox.
This is the recommended command before LOGOUT.
copy(message_set, new_mailbox)- Copy message_set messages onto end of new_mailbox.
create(mailbox)- Create new mailbox.
delete(mailbox)- Delete old mailbox.
enable(capability)- Send an RFC5161 enable string to the server.
EG: ask the server to enable UTF-8 message encoding:
if 'ENABLE' in imapobj.capabilities:
imapobj.enable("UTF8=ACCEPT")
enable_compression()- Ask the server to start compressing the connection.
Should be called from user of this class after instantiation, as in:
if 'COMPRESS=DEFLATE' in imapobj.capabilities:
imapobj.enable_compression()
examine(mailbox='INBOX')- Select a mailbox for READ-ONLY access.
Flush all untagged responses.
Returned data is count of messages in mailbox (EXISTS response).
Mandated responses are
'FLAGS', 'EXISTS', 'RECENT', 'UIDVALIDITY',
so other responses should be obtained by calling response('FLAGS') etc.
expunge()- Permanently remove deleted items from selected mailbox.
Generates an EXPUNGE response for each deleted message.
Returned data contains a list of EXPUNGE message numbers in order received.
fetch(message_set, message_parts)- Fetch (parts of) messages.
message_parts should be a string of selected parts
enclosed in parentheses, eg: "(UID BODY[TEXT])".
Returned data are tuples of message part envelope and data,
followed by a string containing the trailer.
getacl(mailbox)- Get the Access Control Lists for a mailbox.
getannotation(mailbox_name, entry_specifier, attribute_specifier)- Retrieve ANNOTATIONS.
getquota(root)- Get the quota root's resource usage and limits.
(Part of the IMAP4 QUOTA extension defined in RFC2087.)
getquotaroot(mailbox)- Get the list of quota roots for the named mailbox.
id(field1, value1, ...)- IMAP4 ID extension:
exchange information for problem analysis and determination.
NB: a single argument is assumed to be correctly formatted and is passed through unchanged
(for backward compatibility with earlier version).
The ID extension is defined in RFC 2971.
idle(timeout=None)- Put server into IDLE mode
until server notifies some change,
or timeout (secs) occurs [default: 29 minutes],
or another IMAP4 command is scheduled.
list(directory='""', pattern='*')- List mailbox names in directory matching pattern.
Returned data is list of LIST responses.
login(user, password)- Identify client using plaintext password.
The password argument will be quoted.
login_cram_md5(user, password)- Force use of CRAM-MD5 authentication.
logout()- Shutdown connection to server.
Returns server BYE response.
NB: You must call this to shut down threads before discarding an instance.
lsub(directory='""', pattern='*')- List subscribed mailbox names in directory matching pattern.
Returned data are tuples of message part envelope and data.
myrights(mailbox)- Show my Access Controll Lists for mailbox
(i.e. the rights that I have on mailbox).
namespace()- Returns IMAP namespaces per RFC2342.
noop()- Send NOOP command.
partial(message_num, message_part, start, length)- Fetch truncated part of a message.
Returned data is tuple of message part envelope and data. NB: obsolete.
pop_untagged_responses()- (Helper method.)
Generator for obtaining untagged responses.
Returns and removes untagged responses in order of reception.
Use at your own risk!
(Removing untagged responses required by outstanding commands may cause errors.)
proxyauth(user)- Assume authentication as user.
(Allows an authorised administrator to proxy into any user's mailbox.)
recent()- (Helper method.)
Return RECENT responses if any exist,
else prompt server for an update using the NOOP command.
Returned data is
None if no new messages,
else list of RECENT responses, most recent last.
rename(oldmailbox, newmailbox)- Rename old mailbox name to new.
response(code)- (Helper method.)
Return data for response code if received, or None.
Response value is cleared.
Returns the given code in place of the usual type.
search(charset, criterium, ...)- Search mailbox for matching messages.
Returned data contains a space separated list of matching message numbers.
select(mailbox='INBOX', readonly=False)- Select a mailbox.
Flush all untagged responses.
Returned data is count of messages in mailbox (EXISTS response).
Mandated responses are
'FLAGS', 'EXISTS', 'RECENT', 'UIDVALIDITY',
so other responses should be obtained by calling response('FLAGS') etc.
setacl(mailbox, who, what)- Set the Access Control Lists for a mailbox.
setannotation(mailbox_name, entry, attribute_value[, entry, attribute_value]*)- Set ANNOTATIONS.
setquota(root, limits)- Set the quota root's resource limits.
sort(sort_criteria, charset, search_criteria, ...)- IMAP4rev1 extension SORT command.
starttls(keyfile, certfile, ca_certs, cert_verify_cb, ssl_version="ssl23", tls_level="tls_compat")- Start TLS negotiation as per RFC 2595.
If non-null, cert_verify_cb will be called to verify the server certificate,
with peer certificate and hostname as parameters.
If cert_verify_cb returns a non-null response, an SSL exception will be raised with the response as reason.
starttls should be called from user of the IMAP4 class after instantiation, as in:
if 'STARTTLS' in imapobj.capabilities:
imapobj.starttls()
The recognized values for tls_level are:
- tls_secure: accept only TLS protocols recognized as "secure"
- tls_no_ssl: disable SSLv2 and SSLv3 support
- tls_compat: accept all SSL/TLS versions
status(mailbox, names)- Request named status conditions for mailbox.
store(message_set, command, flag_list)- Alters flag dispositions for messages in mailbox.
subscribe(mailbox)- Subscribe to new mailbox.
thread(threading_algorithm, charset, search_criteria, ...)- IMAP4rev1 extension THREAD command.
uid(command, arg, ...)- Execute
command arg ... with messages identified by UID,
rather than message number.
Returns response appropriate to command.
unsubscribe(mailbox)- Unsubscribe from old mailbox.
xatom(command, arg, ...)- Allow simple extension commands as
notified by server in CAPABILITY response.
Returns response appropriate to command.
IMAP4 instances have a variable, PROTOCOL_VERSION,
that is set to the most recent supported protocol in the CAPABILITY response.
Usage
Here is a minimal example (without error checking) that opens a mailbox
and retrieves and prints all messages:
def cb(cb_arg_list):
response, cb_arg, error = cb_arg_list
typ, data = response
if not data:
return
for field in data:
if type(field) is not tuple:
continue
print('Message %s:\n%s\n'
% (field[0].split()[0], field[1]))
import getpass, imaplib2
M = imaplib2.IMAP4()
M.LOGIN(getpass.getuser(), getpass.getpass())
M.SELECT(readonly=True)
typ, data = M.SEARCH(None, 'ALL')
for num in data[0].split():
M.FETCH(num, '(RFC822)', callback=cb)
M.CLOSE()
M.LOGOUT()
Note that IMAP4 message numbers change as the mailbox changes,
so it is highly advisable to use UIDs instead via the UID command.
At the end of the module,
there is a test section that contains a more extensive example of usage.

"""Threaded IMAP4 client class.
Instantiate with:
IMAP4(host=None, port=None, debug=None, debug_file=None, identifier=None, timeout=None, debug_buf_lvl=None)
host - host's name (default: localhost);
port - port number (default: standard IMAP4 port);
debug - debug level (default: 0 - no debug);
debug_file - debug stream (default: sys.stderr);
identifier - thread identifier prefix (default: host);
timeout - timeout in seconds when expecting a command response (default: no timeout),
debug_buf_lvl - debug level at which buffering is turned off.
All IMAP4rev1 commands are supported by methods of the same name.
Each command returns a tuple: (type, [data, ...]) where 'type'
is usually 'OK' or 'NO', and 'data' is either the text from the
tagged response, or untagged results from 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).
Errors raise the exception class .error("").
IMAP4 server errors raise .abort(""), which is
a sub-class of 'error'. Mailbox status changes from READ-WRITE to
READ-ONLY raise the exception class .readonly(""),
which is a sub-class of 'abort'.
"error" exceptions imply a program error.
"abort" exceptions imply the connection should be reset, and
the command re-tried.
"readonly" exceptions imply the command should be re-tried.
All commands take two optional named arguments:
'callback' and 'cb_arg'
If 'callback' is provided then the command is asynchronous, so after
the command is queued for transmission, the call returns immediately
with the tuple (None, None).
The result will be posted by invoking "callback" with one arg, a tuple:
callback((result, cb_arg, None))
or, if there was a problem:
callback((None, cb_arg, (exception class, reason)))
Otherwise the command is synchronous (waits for result). But note
that state-changing commands will both block until previous commands
have completed, and block subsequent commands until they have finished.
All (non-callback) string arguments to commands are converted to bytes,
except for AUTHENTICATE, and the last argument to APPEND which is
passed as an IMAP4 literal. NB: the 'password' argument to the LOGIN
command is always quoted.
There is one instance variable, 'state', that is useful for tracking
whether the client needs to login to the server. If it has the
value "AUTH" after instantiating the class, then the connection
is pre-authenticated (otherwise it will be "NONAUTH"). Selecting a
mailbox changes the state to be "SELECTED", closing a mailbox changes
back to "AUTH", and once the client has logged out, the state changes
to "LOGOUT" and no further commands may be issued.
Note: to use this module, you must read the RFCs pertaining to the
IMAP4 protocol, as the semantics of the arguments to each IMAP4
command are left to the invoker, not to mention the results. Also,
most IMAP servers implement a sub-set of the commands available here.
Note also that you must call logout() to shut down threads before
discarding an instance.
