So, basically, no? What would I have to supply to use system

Maildrop is maildir++ compatible. I assume that this new code
deviates from the maildir++ standard?

OK. So, when vdelivermail delivers a message to the maildir, it just
modify's the quota based on the email's size, correct? It doesn't
actually recalculate the entire quota?

What happens when an IMAP or POP server deletes a message from the
maildir? Is the quota then incorrect? I use Courier-IMAP.

Is there a way to recalculate a user's maildir quota via command line?
(For instance, so that all of my user's quotas could be recalculated at
4 AM from scratch via a shell script or Perl script?)

Thanks for all the info!
