My apologies, I didn’t read your last sentence. If you are running a recent version of Postfix you can use postscreen.

Recently, I get every 4 minutes a connection from IP 155.133.82.96, which appears to be Windows XP and maybe has a virus. Anyway, I found the way (after a lot of Googling) to make my Postfix not delay client access checks and I reject that IP based on a custom blacklist. However, it stays around for a while. I want to find a more radical way to forcibly disconnect the IP when the check has finished and the IP hasn't passed it. How can I do that? (I seek a Postfix solution, not iptables or similar) ________________________________ Since 1982, Starpoint Solutions has been a trusted source of human capital and solutions.
