7.18 I am still getting bombarded with spp_portscan messages even though the IP that I am getting the portscan from is in my $DNS_SERVERs var

Try adding /32 netmasks to those addresses: 

var DNS_SERVERS \[xxx.xx.0.3/32,xxx.xxx.0.2/32\]

And make sure the $DNS_SERVERS variable is on the portscan-ignorehosts line: 

preprocessor portscan-ignorehosts: $DNS_SERVERS
