Here is a script I used to migrate my boxes from mbox to maildir:

I also use dovecot and it has no problems to recognize the change from
mbox to maildir.

I don't know about ext3 but ufs on OpenBSD and XFS on linux 2.6 don't
have a real problem handling 20000+ files in one folder. My thought is
that reiserfs is probably a better choice for a maildir setup as it is
designed to perform well with thousands of small files.
