I am new to the list.
This is on OS-X Server 10.6.3 on an Xserve with postfix 2.5.5 that came
with the system.
I have a situation where using zen.spamhaus.org , spam gets through
despite zen saying that IP is bad.
here is a sample error message:
connect from cpe-67-252-139-22.buffalo.res.rr.com [220.127.116.11]
May 19 01:09:15 velo postfix/smtpdP26473]: warning:
18.104.22.168.zen.spamhaus.org: RBL lookup error: Host or domain name
not found. Name service error for name=22.214.171.124.zen.spamhaus.org
type=A: Host not found, try again
Is it possible that the postfix software barfs when the RBL lookup
returns multiple responses and lets the messsage through ?
Is there a way to fix this (other than removing zen and adding the
individual lists it contains) ?
This is a low volume server. And if I exceeded my daily quota, wouldn't
the nslookup command also fail ?
