If the backend IMAP server is using mbox for mail storage, then you'll want
to turf it. There's not way this will work in any kind of safe, fast, or
reliable way. mbox is not suited to even hundreds of messages in a single
folder.
If the backend IMAP server does not use server-side sorting, server-side
threading, and server-side filtering, then you'll want to enable those
before accessing it via any IMAP client. If the IMAP server doesn't support
those, then turf if. There's no way this will work if you have to process
everything in the client.
Finally, disable local mail filters in SquirrelMail. And configure it to
use server-side threading and sorting.
One you have a robust IMAP server that handles all the processing (sorting,
threading, filtering, etc) on the server, then SM will work fine. I have
several accounts with hundreds of folders, thousands of messages,
multiple-GB of used storage, and things are very snappy in SM 1.5.1. But
that's with Cyrus IMAP on the backend doing all the heavy lifting.
