"Get the emails where you need them."

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

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.

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.

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.

GNU General Public License v2.

You should first check if your distribution already packages OfflineIMAP for you. Downloads releases as tarball or zipball.

If you are running Linux/BSD, you can install offlineimap with:

• Fedora dnf install offlineimap
• FreeBSD pkg search offlineimap3, and install the python versioned package, pkg install py311-offlineimap3
• Arch Linux: pacman -S offlineimap, or through AUR package offlineimap3-git
• Docker image: offlineimap/offlineimap:latest (note: image not published yet, just an example)

The user discussions, development, announcements and all the exciting stuff take place on the mailing list. While not mandatory to send emails, you can subscribe here.
