Introduction

IMAPClient is an easy-to-use, Pythonic and complete IMAP client library.

Although IMAPClient actually uses the imaplib module from the Python standard library under the hood, it provides a different API. Instead of requiring that the caller performs extra parsing work, return values are full parsed, readily usable and use sensible Python types. Exceptions are raised when problems occur (no error checking of return values is required).

IMAPClient is straightforward to use, but it can be useful to have at least a general understanding of the IMAP protocol. RFC 3501 explains IMAP in detail. Other RFCs also apply to various extensions to the base protocol. These are referred to in the documentation below where relevant.

Python versions 3.4 through 3.9 are officially supported.

Getting Started

Install IMAPClient:

$ pip install imapclient

See Installation for more details.

The core of the IMAPClient API is the IMAPClient class. Instantiating this class, creates a connection to an IMAP account. Calling methods on the IMAPClient instance interacts with the server.

The following example shows a simple interaction with an IMAP server. It displays the message ID, subject and date of the message for all messages in the INBOX folder.

>>> from imapclient import IMAPClient
>>> server = IMAPClient('imap.mailserver.com', use_uid=True)
>>> server.login('someuser', 'somepassword')
b'[CAPABILITY IMAP4rev1 LITERAL+ SASL-IR [...] LIST-STATUS QUOTA] Logged in'

>>> select_info = server.select_folder('INBOX')
>>> print('%d messages in INBOX' % select_info[b'EXISTS'])
34 messages in INBOX

>>> messages = server.search(['FROM', 'best-friend@domain.com'])
>>> print("%d messages from our best friend" % len(messages))
5 messages from our best friend

>>> for msgid, data in server.fetch(messages, ['ENVELOPE']).items():
>>>     envelope = data[b'ENVELOPE']
>>>     print('ID #%d: "%s" received %s' % (msgid, envelope.subject.decode(), envelope.date))
