Hi all, I've read this tutorial, and also successfully used falko's tutorial about postfix and courier. I'm thinking about using this setup to create a spam gateway. The server will not have users, but will simply face the internet, receive mails for a given domain, filter them and then forward them to the "real" mail server. Is it correct to simply have in the database a single instance in the transport table as: example.com smtp:[18.104.22.168] Using mailwatch I can watch at filtered email and eventually release them to the transport. Is it ok? Can I also avoid to install courier since noone will download mail..... Thanks, Luca.
