I've had problems with spamhaus hating my DNS proxy on my watchguard firewall. Had to turn off the proxy. Another issue I had recently with spamhaus is that public DNS servers like 8.8.8.8 and 4.4.2.2 don't work. But that should actually allow all traffic, so forget that I guess.
By everything do you mean EVERYTHING? I was seeing the same NDRs for many Gmail clients earlier this week because about 80 gmail servers are blacklisted by spamcop. But non gmail traffic gets in fine. -Bill On Fri, Feb 11, 2011 at 8:44 AM, Kennedy, Jim <[email protected]>wrote: > Trying to resolve the spamhaus.org zones to an A record will not work, it > is a defensive measure against DoS attacks.
