Hi, i use a external spamfilter, and problem now is that spam get delivered directly to my server, how can ispconfig only accept mail from the spamfilter?
One possibility is to use a iptables rule to limit access to port 25 to the ip address of the spamfilter.
Fixed like this: iptables -A INPUT -p tcp --dport 25 -s spamfilterIP -j ACCEPT iptables -A INPUT -p tcp --dport 25 -j DROP
