Yeah, same here, but the way I figure it is it's surely better to
conserve the disk space if at all possible ;)

I can confirm they both do ;)  I assume you mean Courier-IMAP and not
the Courier MTA.  It sucks.  Postfix or Exim are much better ;)

Yeah, right now I'm using NFS mounts, which is a bit ugly, to say the
least.  Since I had troubles with union I steered clear of nullfs, since
the same ``slippery dog'' warning exists ;)

  Thanks very much for sharing your ideas, eventually somebody will
write a jail HOWTO that covers all of the different methods of achieving
these things... I hope ;)
