Well: I am working with Maildir mailstores, so I guess I need to
have a uidlist kinda file then? Sorry it wasn't clear in my post 
that I am using Maildir style mailboxes... But I figured maildir was
better than Mbox over nfs...

My current setup is with postgresql and Maildir. So in a way, a lot of
info COULD come from my database, if it isn't safe enough via nfs.

Can you make all file locking configurable? Or will you do it on a 
"per-type" basis? (eg: mailbox locking, index locking, flag-file locking,
etc).
