# This is the openspf.org test suite (release 2014.04) based on RFC 7208.
# http://www.openspf.org/Test_Suite
#
# $Id$
# vim:sw=2 sts=2 et
#
# See rfc7208-tests.CHANGES for a changelog.
#
# Contributors:
#   Stuart D Gathman    90% of the tests
#   Julian Mehnle       some tests, proofread YAML syntax, formal schema
#   Frank Ellermann
#   Scott Kitterman
#   Wayne Schlitt
#   Craig Whitmore
#   Norman Maurer
#   Mark Shewmaker
#   Philip Gladstone
#
# For RFC 4408, the test suite was designed for use with SPF (type 99) and TXT
# implementations.  In RFC 7208, use of type SPF has been removed.
#
# The "Selecting records" test section is the only one concerned with weeding
# out (incorrect) queries for type SPF of any kind or proper response to
# duplicate or conflicting records.  Other sections rely on auto-magic
# duplication of SPF to TXT records (by test suite drivers) to test all
# implementation types with one specification.
#
# All new tests should use Documentation IPs for both IP4 and IP6.  I was
# stupid to use 1.2.3.4 - that is a real global IP (although it doesn't ping).

      Because TXT records is where v=spf1 records will likely be, returning
      temperror will try again later.  A timeout due to a braindead server
      is unlikely in the case of TXT, as opposed to the newer SPF RR.

      An empty domain label, i.e. two successive dots, in a mechanism
      target-name is valid domain-spec syntax (perhaps formed from a macro

      Going from the "toplabel" grammar definition, an implementation using
      regular expressions in incrementally parsing SPF records might
      erroneously try to match a TLD such as ".xn--zckzah" (cf. IDN TLDs!) to
      '( *alphanum ALPHA *alphanum )' first before trying the alternative
      '( 1*alphanum "-" *( alphanum / "-" ) alphanum )', essentially causing
      a non-greedy, and thus, incomplete match.  Make sure a greedy match is

    comment: >-
      The result of this test cannot be permerror not only because the
      RFC does not specify it, but because the sender has no control over
      the PTR records of spammers.
      The preferred result reflects evaluating the 10 allowed PTR records in
      the order returned by the test data.
      If testing with live DNS, the PTR order may be random, and a pass
      result would still be compliant.  The SPF result is effectively
      randomized.

      There seems to be a tendency for developers to want to limit
      A RRs in addition to MX and PTR.  These are IPs, not usable for
      3rd party DoS attacks, and hence need no low limit.
