General tip, why do you need a second mail system for this? Postfix
could just call maildrop itself which would be responsible for calling
SA and filtering. The simpler your system is, the fewer problems you'll
have, but you may have your reasons for having 2 servers...

Why not? If they don't have accounts they can't do anything with them
anyway. I have some users forwarding on to a old install of
Mercury/Pegasus Mail, they exist in LDAP so all Courier has for them is
a home directory. I have LDAP_MAILROOT set to /var/maildir and
LDAP_HOMEDIR set to the uid attribute. I have a cron script that checks
for new or removed LDAP accounts so I don't have to do anything when new
users are created in the LDAP directory.
