I have a lot of warnings like this below in my logs. Why is that and how can I correct this?

mail postfix/dnsblog[25349]: warning: dnsblog_query: lookup error for DNS query 161.170.123.180.zen.spamhaus.org: Host or domain name not found. Name service error for name=161.170.123.180.zen.spamhaus.org type=A: Host not found, try again

It also looks like the name resolving is just fine because:

# host 161.170.123.180.zen.spamhaus.org
;; connection timed out; no servers could be reached

but:

# host google.com
google.com has address 173.194.76.138
google.com has address 173.194.76.113
google.com has address 173.194.76.102
google.com has address 173.194.76.100
google.com has address 173.194.76.139
google.com has address 173.194.76.101
google.com has IPv6 address 2a00:1450:4007:814::200e
google.com mail is handled by 40 alt3.aspmx.l.google.com.
google.com mail is handled by 10 aspmx.l.google.com.
google.com mail is handled by 50 alt4.aspmx.l.google.com.
google.com mail is handled by 30 alt2.aspmx.l.google.com.
google.com mail is handled by 20 alt1.aspmx.l.google.com.
  • Please try check your nameservers. Probably it dns resolving. – Meiram Chuzhenbayev Jan 3 '18 at 10:19
  • I don't think so. I can do: host google.com and it gives me the correct IP – Kornel Jan 8 '18 at 20:19
