Package: libmail-spf-perl Version: 2.9.0-5 In case of clients with IPv6 addresses, Mail::SPF counts non existing AAAA-Records as void dns lookups, although valid A-Records does exist. Correct behaviour would be to count only as void lookups, if neither A- nor AAAA-Record exists.
Example:
spftest.dfn.de TXT "v=spf1 a a:one.spftest.dfn.de
a:two.spftest.dfn.de -all"
spftest.dfn.de A 194.94.252.247
one.spftest.dfn.de A 194.94.252.253
two.spftest.dfn.de A 194.94.252.254
Test 1:
$ echo "192.107.51.3 t...@spftest.dfn.de mail.enea.it" | spfquery -f - -s mfrom
fail
Rejected by SPF record
spftest.dfn.de: Sender is not authorized by default to use
't...@spftest.dfn.de' in 'mfrom' identity (mechanism '-all' matched)
Received-SPF: fail (spftest.dfn.de: Sender is not authorized by default to use
't...@spftest.dfn.de' in 'mfrom' identity (mechanism '-all' matched))
receiver=mgw6-han.srv.dfn.de; identity=mailfrom;
envelope-from="t...@spftest.dfn.de"; helo=mail.enea.it; client-ip=192.107.51.3
$
Test 2:
$ echo "2a00:1450:4864:20::34a t...@spftest.dfn.de mail-wm1-x34a.google.com" |
spfquery -f - -s mfrom
permerror
spftest.dfn.de: Maximum void DNS look-ups limit (2) exceeded
spftest.dfn.de: Maximum void DNS look-ups limit (2) exceeded
Received-SPF: permerror (spftest.dfn.de: Maximum void DNS look-ups limit (2)
exceeded) receiver=mgw6-han.srv.dfn.de; identity=mailfrom;
envelope-from="t...@spftest.dfn.de"; helo=mail-wm1-x34a.google.com;
client-ip="2a00:1450:4864:20::34a"
$
Expectation: test 2 should give the same result as test 1.
