# OfflineIMAP

***"Get the emails where you need them."***

[Official offlineimap][https://github.com/OfflineIMAP/offlineimap3].


## Description

OfflineIMAP is software that downloads your email mailbox(es) as **local
Maildirs**. OfflineIMAP will synchronize both sides via *IMAP*.

## Why should I use OfflineIMAP?

IMAP's main downside is that you have to **trust** your email provider to
not lose your email. While certainly unlikely, it's not impossible.
With OfflineIMAP, you can download your Mailboxes and make you own backups of
your [Maildir](https://en.wikipedia.org/wiki/Maildir).

This allows reading your email offline without the need for your mail
reader (MUA) to support IMAP operations. Need an attachment from a
message without internet connection? No problem, the message is still there.


## Project status and future

OfflineIMAP, using Python 3, is based on OfflineIMAP for Python 2.
Currently we are updating the source code. These changes should not affect
the user (documentation, configuration files,... are the same) but some
links or packages could refer to the Python 2 version. In that case, please
open an issue.
