Really intresting point of view, i need to spend more time on it.
About resource consuming .. i have to check/match my resource/snmp
monitoring to better evaluate. I'm now using few (and quite light
resource consuming) pcre rules and they kill about 60-80% of potential
dnsbl-ed senders. I've given a rapid sight at system graphics now and
during the 2 days of my postscreen dnsbl tests i've noticed more dns
look-up and cpus resources pretty unchanged ..
But consider the system flow has not been altered to well integrate
postscreen (only a rapid test); so i'm sure you are right when you say
"postscreen changes the calculation of costs" !
Have someone already done fine check resource consumption comparisons?
I'm going to play more with ..
Ciao e buon week-end!
