I have the following error message in my /var/log/spamd

spf: lookup failed: available_nameservers: No DNS servers available!

Having Googled the error message I've found a number of responses which involve patching Perl or Spamassassin or other cures.

Before I start changing things I was wondering if there was a Centos 7 specific resolution. Where possible, on production machines I prefer to stay with RPM's rather than amending software directly.

I run SpamAssassin on CentOS 7; the SPF plugin is loaded via /etc/mail/spamassassin/init.pre. I have no trouble with spf at all.

Is it possible the problem is with local DNS resolution?
