> 1. Setup with the blocklist sbl.spamhaus.org edit a courier configuration file called "esmtpd" and set this one: BLACKLISTS="-block=zen.spamhaus.org,BLOCK"
> 2. Allow complete relaying privileges to all clients NOT on the blocklist this is not a good idea. If your MTA is exposed to the internet you'll get blacklisted in 10 minutes all over the world due to the fact that you are an open relay. This is also not good for internet. > 3. Require authentication of clients on the blocklist, but allow them > complete relaying privileges after successful authentication. you can setup relaying privileges without authentication using the smtp client ip address, but I'm not sure if courier will let your mail going on if the client ip address is dns blacklisted, nor it's a good idea at all Please think twice before setting up a mail server this way if it is going to play in internet!
