If you have filesystem corruption occurring, that means you have an
unstable system. You can't blame anything else that breaks on the
software or design; most software assumes that the filesystem works.
I've got a server here with ~28000 mailboxes (not all get much mail;
probably around ~20000 active mailboxes), and it works just fine with
standard mbox format mailboxes. Of course, the first thing I did was
rip out qpopper, as it was corrupting mailboxes on a regular basis.
The problem with Maildir is that it writes each message to a file by
itself. News server operators figured out 4-5 years ago that that was a
bad design. It works okay when you have no more than 50 messages in a
mailbox, but it doesn't scale up well when you get lots of messages in a
mailbox (which happens all too often - when I go away for vacation for a
week, I'll come back to a couple of thousand messages).
Mbox isn't perfect by any means, but neither is Maildir; mbox has the
advantage that virtually every program written to handle mail under Unix
can handle it.

I don't speak for anybody but myself - that's enough trouble.
