Hello All,
I ran a few DNS tests against OpenDNS and I won't say it works
"splendidly" as they describe it. In summary, don't use OpenDNS on your
mail server.
- does NOT resolve fake MX records
- does resolve A records for fake records
So, if you run a mail server with anti-spam checks against no MX or
A records, don't use OpenDNS or turn off this test since it won't be
effective.

I run a mail server. May I use OpenDNS?
OpenDNS resolution works splendidly for mail servers. As of August 31,
2006, that includes those mail servers running a DNS real-time blacklist
(DNSBL).
