Frankly, I would say: you shouldn't.

In general, running a single SpamAssassin filter on a mail server with multiple
users (especially if their email addresses are in multiple domains) gives far
poorer results than doing per-user Bayes learning.

By combining the spam / ham folders over multiple machines, you're just
exacerbating the problem.

So, my recommendation is to keep each user's mail feed separate, run
SpamAssassin so that it uses per-user Bayes databases, and save yourself the
work of combining the folders from multiple servers.
