You need to patch Exim to do this. If you use the netfilter (aka iptables) REDIRECT target, the original destination address can be fetched from the socket using getsockopt(...SO_ORIGINAL_DST...). This needs to be done inside Exim. If you want to reject anything anyway you could just hack up a small SMTP responder instead. You can also use Perl for that, IO::Socket seems to have a getsockopt method. /tom -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
