I attempted to replace procmail with maildrop on my mailserver.  Can't
be done the way I want it.  I use procmail with a system wide set
of rules.  Two of my spam related rules are "save copies in mbox
spam-bogofilter" and then "put the message in the administrator's mbox,
rather than the user's mbox".  Since procmail runs as root, the
mailboxes are all accessible.  

AFAICT, maildrop can only run as a user and can only have rules for a
single user.  That prevents changing mboxs for delivery.  I spent some
time on the maildrop mailing list discussing this limitation, to little
effect.  Sigh....
