Blacklist blocking is a function of the email proxy, not of DNS (the information is served by DNS, but requested by the email proxy).
Filters /always/ come before services (which is why you must have a filter in place to use the email proxy, inbound tunnels, etc).
I'm using dul.dnsbl.sorb.net which is a list of dynamic IP ranges used by ISP for dialup/xDSL/Cable. I also defined my own list with GB object addresses and a filter on port 25. My own filter comes before the filter used by the SMTP proxy. If I place the SMTP proxy filter before my own filter will this also change the order of checking (so the DNS-BL's defined in the SMTP proxy are checked before my own filter)?
