Tool to copy IMAP folders from one server to another

Question

I need a Unix-based tool, such as a shell script or command-line program, to copy IMAP folders from one server to another. Ideally, the tool should copy all the folders for a single account (Inbox, Sent, Trash, and user-created folders) at once, rather than one folder at a time. It should preserve message dates. As an option, I'd like to be able to copy just a single IMAP folder.

Alternatively, is there a tool to copy an mbox file to an IMAP server? I have direct access to the mbox files in the filesystem, but not to the filesystem of the remote IMAP server.

Edit: Is there a way for a user to migrate their own questions to Server Fault?

This program works like a charm! – Barry Brown Feb 19 '09 at 07:51
imapsync is no longer free. It costs about $35. But it still works quite well. – Barry Brown Dec 15 '10 at 19:47
great tool, it worth the money, i have some great experiences using it when it was free. – Paul Feb 05 '11 at 06:47
Happens to be free on macports: https://trac.macports.org/browser/trunk/dports/mail/imapsync/Portfile – Randy Sugianto Jan 26 '12 at 11:53
I found it on [GitHub](https://github.com/imapsync/imapsync) released under a "NO LIMIT PUBLIC LICENSE" in June of 2012. It looks like a solid package; probably worth paying for it if it works for a big migration. – tomlogic Jan 02 '13 at 02:03

Take a look at offlineimap - it can sync multiple imap servers, do server-to-maildir, and probably the other way around as well.

A +1 for offlineimap -- which has a Debian package, by the way, so you can easily `apt-get offlineimap`. A brilliant tool for replicating mailboxes. – Jeremy McGee May 08 '11 at 09:12
It seems to work well. It's too bad the author thinks his documentation is all that. You better grab the example file from GIT: https://github.com/OfflineIMAP/offlineimap/blob/master/offlineimap.conf Of course the version that's in Squeeze is not the latest. So beware. It works for Gmail BTW. – d-_-b Oct 15 '12 at 02:59

To save others the chain of links, offlineimap has moved here: http://offlineimap.org/ – Klox Dec 26 '12 at 21:04

I'm a "fan" of these perl utils: http://www.athensfbc.com/imap_tools/ and have used them a fair bit
