Guide

Basic

from imap_tools import MailBox, Q

# get list of email subjects from INBOX folder
with MailBox('imap.mail.com').login('[e-mail]', 'password') as mailbox:
    subjects = [msg.subject for msg in mailbox.fetch()]

# OR the same otherwise
mailbox = MailBox('imap.mail.com')
mailbox.login('[e-mail]', 'password', initial_folder='INBOX')
subjects = [msg.subject for msg in mailbox.fetch(Q(all=True))]
mailbox.logout()

MailBox.fetch - email message generator, first searches email ids by criteria, then fetch and yields emails by one:

• criteria: message search criteria, docs

• 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

• miss_no_uid: True, miss emails without uid

• mark_seen: True, mark emails as seen on fetch

Email attributes

# NOTE: All message properties are cached by functools.lru_cache

for message in mailbox.fetch():
    message.uid          # str or None: '123'
    message.subject      # str: 'some subject'
    message.from_        # str: '[e-mail]'
    message.to           # tuple: ('[e-mail]', '[e-mail]', )
    message.cc           # tuple: ('[e-mail]', )
    message.bcc          # tuple: ('[e-mail]', )
    message.date         # datetime.datetime: 1900-1-1 for unparsed, may be naive or with tzinfo
    message.date_str     # str: original date - 'Tue, 03 Jan 2017 22:26:59 +0500'
    message.text         # str: 'hi'
    message.html         # str: '<b>hi</b>'
    message.flags        # tuple: ('SEEN', 'FLAGGED', 'ENCRYPTED')
    message.headers      # dict: {'Received': ('from 1.m.net', 'from 2.m.net'), 'AntiVirus': ('Clean',)}
    for att in message.attachments:  # list: [Attachment objects]
        att.filename     # str: 'cat.jpg'
        att.content_type # str: 'image/jpeg'
        att.payload      # bytes: b'\xff\xd8\xff\xe0\'
    message.obj          # email.message.Message: original object
    message.from_values  # dict or None: {'email': '[e-mail]', 'name': 'Ivan', 'full': 'Ivan <[e-mail]>'}
    message.to_values    # tuple: ({'email': '', 'name': '', 'full': ''},)
    message.cc_values    # tuple: ({'email': '', 'name': '', 'full': ''},)
    message.bcc_values   # tuple: ({'email': '', 'name': '', 'full': ''},)

Search criteria

Implemented query builder for search logic described in rfc3501. See query examples.

• Class AND and its alias Q are used to combine keys by the logical “and” condition.

• Class OR is used to combine keys by the logical “or” condition.

• Class NOT is used to invert the result of a logical expression.

• Class H (Header) is used to search by headers.

If the “charset” argument is specified in MailBox.fetch, the search string will be encoded to this encoding. You can change this behavior by overriding MailBox._criteria_encoder or pass criteria as bytes in desired encoding.

from imap_tools import Q, AND, OR, NOT
# allowed types
mailbox.fetch(Q(subject='weather'))  # query, the str-like object
mailbox.fetch('TEXT "hello"')  # str
mailbox.fetch(b'TEXT "\xd1\x8f"')  # bytes
# AND
Q(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
Q(OR(from_='[e-mail]', text='"the text"'), NOT(OR(Q(answered=False), Q(new=True))), to='[e-mail]')
# encoding
mailbox.fetch(Q(subject='привет'), charset='utf8')  # 'привет' will be encoded by MailBox._criteria_encoder
# python note: you can't do: Q(text='two', NOT(subject='one'))
Q(NOT(subject='one'), text='two')  # use kwargs after logic classes

The search key types are marked with * can accepts a sequence of values like list, tuple, set or generator.

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 in folder

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

Result of MailBox.fetch generator will be implicitly converted to uid list.

with MailBox('imap.mail.com').login('[e-mail]', '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.MessageFlags.ANSWERED, imap_tools.MessageFlags.FLAGGED)
    mailbox.flag(mailbox.fetch('(UNSEEN)'), flags, True)

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

Actions with mailbox folders

with MailBox('imap.mail.com').login('[e-mail]', 'pwd') as mailbox:
    # LIST
    for f in mailbox.folder.list('INBOX'):
        print((f['name'], f['flags'], f['delim']))  # ('INBOX|cats', '\\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
    folder_status = mailbox.folder.status('some_folder')
    print(folder_status)  # {'MESSAGES': 41, 'RECENT': 0, 'UIDNEXT': 11996, 'UIDVALIDITY': 1, 'UNSEEN': 5}

Reasons

• Excessive low level of imaplib library.

• Other libraries contain various shortcomings or not convenient.

• Open source projects makes world better.
