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?
Same here, no issues with spamassassin and SPF.
In addition to Paul's question which seems like the most obvious initial
avenue of investigation, I assume you have perl-Mail-SPF and
perl-Net-DNS installed? They should be as both are deps for the
CentOS mailing list
