Possible spamhaus issue??

Brent_Gay
Hey,
I am wondering if anyone else is running into the following message in their SMTP log:

DNS list lookup defer (probably timeout) for x.x.x.x.zen.spamhaus.org: assumed not in list

We just started receiving a large number of these since Nov. 3rd. It does appear that zen.spamhaus is still blocking spam however. Any ideas what has happened? We are running an ASG 425 with 6.311. All DNS is configured correctly and can resolve names without any problem. All is working good except these messages in the SMTP log.

Thanks!
Brent

    Recently, spamhaus.org stopped blocking IPs which were doing a lot of DNS requests exceeding their TOU.

    You may want to check your usage and make sure your DNS server (if not using Astaro's) is doing the proper caching to help reduce your apparent usage.
