I want to sync three imap *servers*. Or at least, two.

You're running Dovecot on the laptop? I don't understand that. If you want to be able to read messages while offline, then just configure your email app to download the messages when downloading, instead of headers only.
No way.
You are saying that I would store my local mail folders, several gigabytes of mail, in local folders in Thunderbird at one computer.
No I am not.
The problem then would become how to sync that Thunderbird local storage with two other computers.
If you were using IMAP properly you wouldn't have this problem. If you were using IMAP alone Thunderbird would re-sync whenever you had connectivity, regardless.
You are thinking of 'download' as an analogue to POP/fetchmail. When T'Bird 'downloads' messages it is in effect caching the IMAP over above what you've actually viewed but not deleting the cache when you log out. So when you reconnect, it resynchronises.
You can do this on a folder by folder not just account by account. So you can download-for-sync under the FolderProperties->Synchronization tab for just the inbox and ignore everything else.
The same happens with K9/K@. Yes it is a data hit, but I have a big microSD card in my tablet & phone for that; a 32G that cost me about C$15. It also have movies and a lot of stuff from Gutenberg and and the transcription of my favourite CDs. By now, 64G chips are getting cheap. Space is not the issue and hasn't been for a long while.
Use IMAP and IMAP alone. It was designed to cope with situation such as you are describing, once you get rid of that superfluous Dovecot server that is screwing up the resynchronisation.
Frankly, it is more reliable and versatile to instead store my local mail folders under my local dovecot server, where I can access it with any mail client in any locally connected computer.
Well, I can't. I simply can not access my home imap server when I'm not at home, so please stop giving absurd recommendations. My network limitations are not yours. The laptop needs a local copy of the server email, and I do this with two dovecot servers, imap, and sync tools, since years. I simple search for better sync tools. I do not care about other proposals. Writing and reading them is a waste of time for both. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas))
