I've been tasked with importing a large bunch of mbox folders (about 500)

As far as I can see, dsync "mirror" or "backup" are both inappropriate ways
of doing this. Does anyone have any suggestions about how I could proceed?
I've done a variety of mail migrations over the years, including some that
were quite large (hundreds of thousands of accounts). I looked at a few
options when doing the first one and ended up concluding that pop/imap was
the best way to go. A specialised migration tool must be less tested (and
perhaps more buggy) than pop/imap servers that are in use around the world
constantly. By using pop/imap proxies we were able to do migrations that
were completely transparent to users.
This presumes that you are migrating from one server to another. I've
always done it like this, rather than having to worry about multiple
storage formats on the one server.

Rob
