I was wonder if it is doable that the outside world can only see ports 587 and 465 while limiting port 25 to localhost only.
a universal solution would be: iptables -A INPUT -s 127.0.0.1/32 -p tcp -m tcp --dport 25 -j ACCEPT iptables -A INPUT -s 0.0.0.0/0 -p tcp -m tcp --dport 25 -j DROP best regards, Marius -- ## List details at https://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/
