https://github.com/OfflineIMAP/offlineimap/archive/v6.7.0.tar.gz

OfflineIMAP is a tool to simplify your e-mail reading. With OfflineIMAP,
you can read the same mailbox from multiple computers. You get a
current copy of your messages on each computer, and changes you make one
place will be visible on all other systems. For instance, you can delete
a message on your home computer, and it will appear deleted on your work
computer as well. OfflineIMAP is also useful if you want to use a mail
reader that does not have IMAP support, has poor IMAP support, or does
not provide disconnected operation.
