ups yeah, Patrick is right about mdbox, but it might be posssible convert mdbox public spam folders to maildir by script with dsync and then sa-learn invoked by cron etc, i see no problem with postfix transport method look something like here http://www.localside.net/sal-wrapper/README.txt after all, i my real big setup, nearly noone uses this the false postive rate is near null, and users have the chance to black/whitelist list their own stuff > > Since you run on SSD maildir shouldn't be a real performance problem.
