server-side sorting makes the IMAP server do the sorting based on
criteria we provide. Server side thread allows the server to build a
thread for us. Depending on your IMAP server, that might be by
subject, or references (a header combination of In-Reply-To and
References), or both. If you look at the headers for this email, you
should see a References header which allows the IMAP server to build a
thread of messages like a tree.

Youch... your IMAP server has to read all 50,000 emails and read the
headers to build the thread for us. That's a bit of a task on its
own. This ultimately ends up generating a load of data (see [1] for
details).

You could edit the code, and set a date criteria on the threading
code. You could do something like this:
functions/imap_messages.php [Line 332]
$date = date('r', strtotime('-1 week'));
$query = 'THREAD ' . $sort_type . strtoupper($default_charset) . $date;
You might need to play around with the code as I've just skimmed on
this, but that should make it only display emails that are a week old
in a threaded format. You can alter $date to be anything that is
defined in RFC3501 in the SEARCH section (See [2]).
