Okay that's exactly the information I was looking for, thanks.  I assume

Jul 27 10:24:02 maus imap(adam): file_wait_lock() failed with index file
/var/maildir/adam/.INBOX/.imap.index: No locks available

Isn't the main point of Maildir (as opposed to mbox) that it *is* NFS 
safe  and doesn't require working locking?
