I've being doing something similar using Mailscanner,
www.mailscanner.info to use as much of the above as scoring inputs to
spam filtering.

My current setup though implements it on a relay server, all mail is
accepted by postfix and dropped into a queue, mailscanner picks up
from that queue, and delivers low scoring mails to the input queue of
another instance of postfix, and we have an in house built "release"
mechanism for quarantined mails, with daily summaries sent to users
about messages which have been blocked.

Now that we have deployed courier as our mailserver, I'd like to
replace the above postfix config with courier. I'd like to keep it on
a "relay" server basis, and have authlib validate incoming mails
against the courier ldap server thus not accepting mails for non
existent accounts.

Is the dual instance of courier and queue lifting and dropping with
mailscanner do'able with courier?

Aine.
