--- Comment #4 from Mel Pilgrim <ports.maintainer@evilphi.com> ---
DEFER_IF_PERMIT and the error message "Unknown error on DNS 'TXT' lookup of
'joules.com'" indicates some transient DNS error, such as a network problem or
DNS misconfiguration.  The error is emitted from Mail::SPF::Server by an
EDNSError exception--entirely internal to the module. policyd-spf-perl is just
a messenger in this case.

I put joules.com through some SPF validation tools and they all passed.  When I
query joules.com with the policyd, I get back DUNNO instead of DEFER_IF_PERMIT.
 Either the error is transient, or it's only in the DNS path between your
postfix instance and joules.com's nameservers.

I did notice that there are a lot of TXT records for joules.com, so perhaps
something isn't handling EDNS0 correctly.
