imap_tools

Work with email and mailbox by IMAP:

  • Parsed email message attributes
  • Query builder for searching emails
  • Actions with emails: copy, delete, flag, move, seen, append
  • Actions with folders: list, set, get, create, exists, rename, delete, status
  • No dependencies

Guide

Basic ^^^^^ .. code-block:: python

from imap_tools import MailBox, AND

get list of email subjects from INBOX folder

with MailBox('imap.mail.com').login('[email protected]', 'pwd') as mailbox: subjects = [msg.subject for msg in mailbox.fetch()]

get list of email subjects from INBOX folder - equivalent verbose version

mailbox = MailBox('imap.mail.com') mailbox.login('[email protected]', 'pwd', initial_folder='INBOX') # or mailbox.folder.set instead 3d arg subjects = [msg.subject for msg in mailbox.fetch(AND(all=True))] mailbox.logout()

MailBox(BaseMailBox), MailBoxUnencrypted(BaseMailBox) - for create mailbox instance.

BaseMailBox.login, MailBox.xoauth2 - authentication functions

BaseMailBox.fetch - email message generator, first searches email nums by criteria, then fetch and yields

MailMessage 
_:
  • criteria = 'ALL', message search criteria,
    query builder 
    _
  • charset = 'US-ASCII', indicates charset of the strings that appear in the search criteria. See rfc2978
  • limit = None, limit on the number of read emails, useful for actions with a large number of messages, like "move"
  • miss_defect = True, miss emails with defects
  • missnouid = True, miss emails without uid
  • mark_seen = True, mark emails as seen on fetch
  • reverse = False, in order from the larger date to the smaller
  • headers_only = False, get only email headers (without text, html, attachments)
  • bulk = False, False - fetch each message separately per N commands - low memory consumption, slow; True - fetch all messages per 1 command - high memory consumption, fast

BaseMailBox. -

copy, move, delete, flag, seen, append 
_

BaseMailBox.folder -

folder manager 
_

BaseMailBox.search - search mailbox for matching message numbers (this is not uids)

BaseMailBox.box - imaplib.IMAP4/IMAP4_SSL client instance.

Email attributes ^^^^^^^^^^^^^^^^

MailMessage and MailAttachment public attributes are cached by functools.lru_cache

.. code-block:: python

for msg in mailbox.fetch():  # iter: imap_tools.MailMessage
    msg.uid          # str or None: '123'
    msg.subject      # str: 'some subject 你 привет'
    msg.from_        # str: 'Sender.Bartö[email protected]'
    msg.to           # tuple: ('[email protected]', '[email protected]', )
    msg.cc           # tuple: ('[email protected]', )
    msg.bcc          # tuple: ('[email protected]', )
    msg.reply_to     # tuple: ('[email protected]', )
    msg.date         # datetime.datetime: 1900-1-1 for unparsed, may be naive or with tzinfo
    msg.date_str     # str: original date - 'Tue, 03 Jan 2017 22:26:59 +0500'
    msg.text         # str: 'Hello 你 Привет'
    msg.html         # str: 'Hello 你 Привет'
    msg.flags        # tuple: ('SEEN', 'FLAGGED', 'ENCRYPTED')
    msg.headers      # dict: {'received': ('from 1.m.ru', 'from 2.m.ru'), 'anti-virus': ('Clean',)}
    msg.size_rfc822  # int: 20664 bytes - size info from server (*useful with headers_only arg)
    msg.size         # int: 20377 bytes

for att in msg.attachments:  # list: imap_tools.MailAttachment
    att.filename             # str: 'cat.jpg'
    att.payload              # bytes: b'\xff\xd8\xff\xe0\'
    att.content_id           # str: '[email protected]'
    att.content_type         # str: 'image/jpeg'
    att.content_disposition  # str: 'inline'
    att.part                 # email.message.Message: original object
    att.size                 # int: 17361 bytes

msg.obj              # email.message.Message: original object
msg.from_values      # dict or None: {'email': '[email protected]', 'name': 'Ya 你', 'full': 'Ya 你 <im>'}
msg.to_values        # tuple: ({'email': '', 'name': '', 'full': ''},)
msg.cc_values        # tuple: ({'email': '', 'name': '', 'full': ''},)
msg.bcc_values       # tuple: ({'email': '', 'name': '', 'full': ''},)
msg.reply_to_values  # tuple: ({'email': '', 'name': '', 'full': ''},)

Search criteria ^^^^^^^^^^^^^^^

This chapter about "criteria" and "charset" arguments of MailBox.fetch.

You can use 3 approaches to build search criteria:

.. code-block:: python

from imap_tools import AND, OR, NOT

mailbox.fetch(AND(subject='weather')) # query, the str-like object mailbox.fetch('TEXT "hello"') # str mailbox.fetch(b'TEXT "\xd1\x8f"') # bytes, *charset arg is ignored

The "charset" is argument used for encode criteria to this encoding. You can pass criteria as bytes in desired encoding - charset will be ignored.

Query builder implements all search logic described in

rfc3501 
_.

======== ===== ========================================== ============================================================ Class Alias Usage Arguments ======== ===== ========================================== ============================================================ AND A combines keys by logical "AND" condition Search keys (see below) | str OR O combines keys by logical "OR" condition Search keys (see below) | str NOT N invert the result of a logical expression AND/OR instances | str Header H for search by headers name: str, value: str UidRange U for search by UID range start: str, end: str ======== ===== ========================================== ============================================================

.. code-block:: python

from imap_tools import A, AND, OR, NOT
# AND
A(text='hello', new=True)  # '(TEXT "hello" NEW)'
# OR
OR(text='hello', date=datetime.date(2000, 3, 15))  # '(OR TEXT "hello" ON 15-Mar-2000)'
# NOT
NOT(text='hello', new=True)  # 'NOT (TEXT "hello" NEW)'
# complex
A(OR(from_='[email protected]', text='"the text"'), NOT(OR(A(answered=False), A(new=True))), to='[email protected]')
# encoding
mailbox.fetch(A(subject='привет'), charset='utf8')
# python note: you can't do: A(text='two', NOT(subject='one'))
A(NOT(subject='one'), text='two')  # use kwargs after logic classes (args)

Server side search notes:

  • For string search keys a message matches if the string is a substring of the field. The matching is case-insensitive.
  • When searching by dates - email's time and timezone are disregarding.

Actions with emails ^^^^^^^^^^^^^^^^^^^

First of all read about uid

at rfc3501 
_.

You can use 2 approaches to perform these operations:

  • "in bulk" - Perform IMAP operation for message set per 1 command
  • "by one" - Perform IMAP operation for each message separately per N commands

MailBox.fetch generator instance passed as the first argument to any action will be implicitly converted to uid list.

For actions with a large number of messages imap command may be too large and will cause exception at server side, use 'limit' argument for fetch in this case.

.. code-block:: python

with MailBox('imap.mail.com').login('[email protected]', 'pwd', initial_folder='INBOX') as mailbox:

# COPY all messages from current folder to folder1, *by one
for msg in mailbox.fetch():
    res = mailbox.copy(msg.uid, 'INBOX/folder1')

# MOVE all messages from current folder to folder2, *in bulk (implicit creation of uid list)
mailbox.move(mailbox.fetch(), 'INBOX/folder2')

# DELETE all messages from current folder, *in bulk (explicit creation of uid list)
mailbox.delete([msg.uid for msg in mailbox.fetch()])

# FLAG unseen messages in current folder as Answered and Flagged, *in bulk.
flags = (imap_tools.MailMessageFlags.ANSWERED, imap_tools.MailMessageFlags.FLAGGED)
mailbox.flag(mailbox.fetch(AND(seen=False)), flags, True)

# SEEN: flag as unseen all messages sent at 05.03.2007 in current folder, *in bulk
mailbox.seen(mailbox.fetch("SENTON 05-Mar-2007"), False)

# APPEND: add message to mailbox directly, to INBOX folder with SEEN flag and now date
with open('/tmp/message.eml', 'rb') as f:
    msg = imap_tools.MailMessage.from_bytes(f.read())  # *or use bytes instead MailMessage
mailbox.append(msg, 'INBOX', dt=None, flag_set=[imap_tools.MailMessageFlags.SEEN])

Actions with folders ^^^^^^^^^^^^^^^^^^^^ .. code-block:: python

with MailBox('imap.mail.com').login('[email protected]', 'pwd') as mailbox:
    # LIST
    for f in mailbox.folder.list('INBOX'):
        print(f)  # {'name': 'INBOX|cats', 'delim': '|', 'flags': ('\\Unmarked', '\\HasChildren')}
    # SET
    mailbox.folder.set('INBOX')
    # GET
    current_folder = mailbox.folder.get()
    # CREATE
    mailbox.folder.create('folder1')
    # EXISTS
    is_exists = mailbox.folder.exists('folder1')
    # RENAME
    mailbox.folder.rename('folder1', 'folder2')
    # DELETE
    mailbox.folder.delete('folder2')
    # STATUS
    stat = mailbox.folder.status('some_folder')
    print(stat)  # {'MESSAGES': 41, 'RECENT': 0, 'UIDNEXT': 11996, 'UIDVALIDITY': 1, 'UNSEEN': 5}
