Is it possible to launch an external script from the ACL? Specifically, when the end
of the acl is reached, instead of just returning the "No relaying allowed" error I also
want to launch a script that slaps down a temporary ip block via iptables. For
performance purposes, I don't want exim to wait for the script to terminate, just fork
it and continue with its own business (shoot and scoot).
I already have a similar system implemented for my web server to deal with some
common exploits like CodeRed and Nimda.
