Tanktalus,
This being postfix, you can set it up to authenticate against either MySQL or LDAP, and one good way to limit spam would be to authenticate the recipient address against a known database of users able to accept email. If it doesn't exist in your authoritative database, throw it away. I'm saying this because the majority of spam I was seeing when I did email for a living (I was an email admin for a small telecom) were generated by dictionary attacks, and this is a simple, trouble free way to get rid of all that. If this is a terminal email acceptor (as opposed to a forwarder), then you might want to grab one of the formulas for building a amavisd-spamassasin-clamav setup as well. Just be warned that this software trio is a power hungry, not suitable for old hardware if you're seeing large volumes of stuff. High volume receivers keep this trio on separate hardware from the original MX acceptor. In reply to Re: PMiltering fun
