I have to move many, many emails (over a thousand) from an old IMAP hosting provider to a new IMAP hosting provider. I know I can just set up the old and new accounts in Thunderbird and drag and drop, but it's very slow and keeps timing out. Is there a better, more automated way to copy all messages (and all mailboxes) between IMAP servers?

There are couple of options you could try:

Use the reliable Mutt (http://www.mutt.org/).
mutt -f imap://username@sourceimaphost/INBOX/foldert, or tag all messages by T and entering ~A.
(With T, you can specify various patterns (http://www.mutt.org/doc/manual/manual-4.html#ss4.2).;s("save") and enter imap://username@destimaphost/INBOX/folder.
(This marks the source messages as deleted(D); if you don't want that, use ;C("copy") instead.)q. You may choose to purge the deleted messages.This allows to move a folder from one account to another. Repeat this for multiple folders.

1You can also use imaps: instead of imap:. If the username part already contains a @ (e.g. as in Google Apps), replace it with %40. Example: imaps://username%40domain.com@imap.gmail.com/INBOX/folder. – musiphil – 2015-08-19T20:41:35.833

Needs cygwin :( and python :( – JDuarteDJ – 2016-01-25T12:41:46.967
@JDuarteDJ: Did you downvote for the reasons you mention!? Given the question puts no restrictions on such things, that would be highly inappropriate. – equaeghe – 2016-01-25T21:08:29.973
@equaeghe I'm sorry that you find it inappropriate. I find that from the question one can understand that the solution should be as simple and direct as possible. I will give you the fact that no OS is mentioned so if one should consider a linux OS these limitations don't apply, I can't take it back but given this I would if I could. – JDuarteDJ – 2016-01-26T11:39:35.417
I didn't know it could do synchronisation too, but it does, and seems stable. Good idea! – qris – 2014-03-06T10:24:34.467

Originally we wrote this article on email migration issues: http://alloraconsulting.com/it-solutions/28-transferring-email-from-one-host-to-another
The article is pretty old, but after many years of occasional bulk migrations from IMAP into Exchange / IMAP it's OpenSource solutions that worked the best, like this one:

You can also use isync/mbsync. Just used it (over a few days, due to quota limits imposed by Google and (specially) Apple) to copy a few dozen thousand emails from Gmail do iCloud. After the copy, deleting the emails on the GMail side was easier and faster (to delete everything) via the web interface.
For continuous retry (after disconnection due to quota limits) until successfully copying everything, one could run it like (bash):
$ while date +"%F %T Restarting..." && ! mbsync channel_name; do sleep 3600; done

Google apps Migration is a good tool, specially with Google Products! – JDuarteDJ – 2016-01-25T12:43:39.450
Wit Google Apps Also note that you are required to set up authorization with a new "console" project in Google. – JDuarteDJ – 2016-01-26T11:34:46.320
