[Exchange] 2003 - DNSBLs and Block List Service Configuration

Just to make sure I understand this correctly:

Exchange Server 2003's -> Block List Server Configuration
If I get a hit on any DNSBL in this list, the email is rejected outright.

There's no weighted score based on DNSBL returns.
There's no option to archive or mark the email (based on DNSBL results) here, only reject it.

Do I understand that correctly?

That seems a rather harsh use of DNSBL. Each false positive would result in an undeliverable email.

Or am I missing something? I hope so.

That's how I understood it to work, if response code = .2 or above then it's spam and message gets rejected.

You can better define action with a 3rd party product like GFI Mail Essentials.
