Well it's certainly a JFS issue, you're right.  JFS does update the mtime when 
files are created ( via open()/creat() ), removed, and renamed into a 
directory.  However, it doesn't update when a new link is created in a 
directory, which is of course how maildir delivery works.  I'll head on over 
to the JFS mailing list to get their input.
