Our Postfix mail server can no longer access the RBL at
zen.spamhaus.org. The maillog has many entries like this one:
Dec 10 17:51:58 zinc postfix/smtpd[11092]: warning:
114.32.177.128.zen.spamhaus.org: RBL lookup error: Host or domain name
not found. Name service error for name=114.32.177.128.zen.spamhaus.org
type=A: Host not found, try again
This seems to have started occurring sometime between late June and
late August(I know. I should pay closer attention to the logs.). I
wonder if we are being blocked. I just reviewed the usage policy
(http://www.spamhaus.org/organization/dnsblusage.html), and our mail
server is nowhere near the limits for free use. Has anyone else had
this happen? Is there any recourse other than paying for a data feed?
FYI, here's a summary of a typical day's email.
