sendmail dnsbl vs MS

[Greg Krzeszkowski]

Hi,

I have a firewall/gateway that forwards smtp to my MS box for processing.   My sendmail.mc has a FEATURE(`dnsbl' ...) for spam/exploit checks, and it regularly (2-3 times a day) causes problems.

I know this is a little off topic, but do I really need the feature included?

This is the kind of sustained error message I receive in my maillog.

Mar 30 13:03:57 localhost sendmail[11731]: ruleset=check_relay, arg1=[192.168.1.254], arg2=192.168.1.254, relay=[192.168.1.254], reject=451 4.7.1 Temporary Lookup failure for 192.168.1.254 in sbl-xbl.spamhaus.org

Cheers
