With maildrop we are talking milliseconds in comparison to the time it
takes to do e-mail virus scanning and spam filtering.  From monitoring
the Postfix list, there appear to be some fairly large sites using
maildrop, and I never hear of any complaints with it.

Maildrop can probably be configure to install the quota file.  Maildrop
also supports quota:

       -w N
           The -w N option places a warning message into the maildir if the
           maildir has a quota setting, and after the message was
successfully
           delivered the maildir was at least N percent full. The warning
           message is copied verbatim from /usr/local/etc/quotawarnmsg with
           the addition of the "Date:" and "Message-Id:" headers. The
warning
           is repeated every 24 hours (at least), until the maildir drops
           below N percent full.

That's fine, you can always add maildirmake to some script that creates
the accounts and the mailboxes at the same time.
