thx for the link. I implemented something similar this: http://robert.penz.name/smtpiptablesblocker/ but I think instead of my script it would be really cool if courier would have something like this integrated. It would be really easy to implement. The courier smtp process sends a 511 error messages, adds the IP address of the spammer to ipt_recent and terminates. The proof of concept is down with my script. Take also a look at the links in the beginning of the text, as they show how I came to this solution and what I tried before and didn't work. -- Regards, Robert ----- Robert Penz ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
