Doesn't the iptables rule block connections from a certain IP? Specifying the address for exim or postfix to listen on is totally different. I suspect what the original poster was asking for was something like: iptables -A INPUT -p tcp -s IP.YOU.WANT.TO.ACCEPT --dport 25 -j ACCEPT iptables -A INPUT -p tcp --dport 25 -j REJECT So accept connections from a single ip, reject the rest. I don't use ip tables directly any more so I'm not sure if I got it right. I'd recommend shorewall even for simple firewall setups at this point, as I find it a nice abstraction over writing iptables rules directly, easier to set policy with, etc. Take care, Dale -- Dale E.
