RE: DNS Blacklist - How do I tell if it's working ~Karl Eknuplopoopsi 4.Mar.03 09:01 AM a Web browser Domino Server 6.0Linux - RedHat
Should the DNSBL stats appear even if no SPAM was blocked?
No - stats are only reported when there is something to report. No DNSBL activity - no stats.
It is possible that I need to open up a TCPIP port for the DNSBL service to use?
Doubt it. DNSBL is just a DNS lookup. If your Domino host can do DNS lookups (and if it delivers outbound mail, then it must do), then DNSBL should work.
To debug further you need to descibe yout set-up more fully.
- what server OS?
- firewall?
- inbound MX topology? (is inbound mail delivered directly to your Domino host, or via a relay host somewhere)?
- DNSBL settings - log only, log and tag, log and reject?
- have you tried the test services offered by ORDB and Spamhaus?
