The first question is how would you make your MTA (postfix or other) talk to spamd. there are a couple of ways: - call spamc at delivery time. This doesn't work for relay gateways, where no delivery is performed. - exec a script that calls spamc. This is not robust, has a few problems (resubmitting mail must be done in a way to avoid loops, ... etc) and is not efficient (fork/exec...) - use a proxy. This proxy can either integrate spamassassin via library calls, which is what amavisd-new does. or it could implement spamc functionality to talk to spamd. amavisd-new can also take decisions: block, quarantine, redirect, ... (spamassassin doesn't care about delivery: it is here to classify the message).
