Howdy folks, I was wondering if anyone happens to know if zen.spamhaus.org is having any sort of troubles? I've noticed an increase in the amount of spam making it through my server, and I checked the mail logs to see about the blacklists. The last time anything was blocked by spamhaus was April 27 in the evening. I usually have several spamhaus hits per day. Anyone else noticing this or did I mess something up on my end and I just haven't realized it yet? Thanks in advance for your help.
Hello, Spamhaus is known to block DNS servers who perform too many queries to their DNS servers. If you use your ISP DNS, it could be the issue. One easy thing to test:
nslookup <reverse_ip>.zen.spamhaus.org @<your dns server> nslookup <reverse_ip>.zen.spamhaus.org @<another dns server>
For example, Google DNS are blocked.
HTH. Jerome
