I've done some searching of the list archives and the web, but I can't lay hands on an answer to this question:

- is there a way, ideally documented in a HOWTO or guide, to configure PostFix such that:

    - it will accept any mail (think "open relay", but...);
    - it will *never* attempt to forward that mail;
- it will *never* generate e-mail: no sent mail, no return receipts, no bounces, nothing?

The application we have in mind is a "Phish Phillet" engine, that would accept any mail sent to it, save the message locally, and process it using a home-grown set of analysis tools - DNS and whois queries, reputational databases, etc. - to rate messages and accumulate statistics about bad-actor mail senders and phishing sites.
