[patch] Mail::SPF::Query

I modified Query.pm to track the totals for DNS queries and cache hits.
I'm wondering if there is any interest in something like this? For an
example of a bad domain to do a SPF chack against see publicaster.com
(229 queries to return fail).

I've attached a patch that I'm using locally.

I thought that an SPF record was invalid (or incorrect) if it caused
more than 10 DNS lookups and that an SPF compliant client was suppose
to stop after 10 DNS lookups. Is this not
correct?

Provided I'm correct, that would seem to me like Mail::SPF::Query is
broken. Isn't this what SpamAssassin uses to do its SPF lookups?

The domain of this list v2.listbox.com needs 13 queries to return a
softfail and pobox.com needs 23 queries to return neutral.

I would've thought if there was a limit of 10 queries that these domains
would be setup correctly.

Cheers,

They are not, that's a known issue, just throw PermError and
reject all mails with SMTP error 550 5.5.2 as specified:

| a limit of 10 MX names MUST be enforced (see Section 10)
[...]
| a limit of 10 PTR names MUST be enforced (see Section 10)
[...]
| if more than 10 sending-domain_names are found, use at most 10.

Odd, why is it an error for MX, but sometimes silently ignored
for PTR ? Checking an "unofficial" -01pre2, yes, it's fixed:

: more than 10 MX names MUST NOT be looked up during the
: evaluation of a "mx" mechanism (see Section 10)
[...]
: more than 10 PTR names MUST NOT be looked up during the
: evaluation of a "ptr" mechanism (see Section 10)
[...]
: if more than 10 sending-domain_names are found, use at most 10.

Back to the last "official" draft-schlitt-spf-classic-00.txt:

| SPF implementations MUST limit the number of mechanism that
| do DNS lookups to at most 10, if this number is exceeded, a
| PermError MUST be returned. The mechanisms that count
| against this limit are "include", "a", "mx", "ptr", "exists"
| and the "redirect" modifier.
[...]
| When evaluating the "mx" and "ptr" mechanisms, or the %{p}
| macro, there MUST be a limit of no more than 10 MX or PTR
| RRs looked up and checked.

The policy publicaster.com text "v=spf1 mx ptr mx:ptr -all"
is completely bogus, mx:ptr is a clear syntax PermError:

| domain-spec = macro-string domain-end
| domain-end = ( "." toplabel ) / macro-expand

No dot, no macro => tilt. Just reject all mails. Bye, Frank

Correct me if i am wrong, but the latest version of Mail::SPF::Query is
2 days away form its one-year birthday, i'd say that makes
Mail::SPF::Query outdated.

In fact, I was wondering what the best SPF implementation is nowadays. I
went for libspf2 1.2.5 despite its compilation errors, wrote a little socket
daemon around it and am going to deploy that now for consultation from
within a milter that does all auth / spam checks.

Perhaps someone knows a solution to a little problem i'm having with
this: Sendmail::Milter allows you to add headers to the message under
scrutiny, however, it does not allow you to add Received-SPF headers in
the proper place. Is this possible at all with milters?? I see there are
three header calls (of which 2 are implemented in Sendmail::Milter):
- addheader
- insertheader
- chheader

Let me guess, it implements addheader but does not implement insheader?

insheader did not exist prior to sendmail 8.13. Unfortunately, when
the sendmail folks added it, they failed to increment the SMFI_VERSION
define in libmilter/mfapi.h - there are versions both with and without
insheader that have SMFI_VERSION == 2. This makes it hard to deal with,
so it wouldn't surprise me if the Sendmail::Milter folks punted and
ignored insheader. Or maybe Sendmail::Milter just hasn't been updated
since sendmail 8.12.

Anyway, it's not that big a deal if the Received-SPF header gets appended
instead of prepended. I don't actually understand why the order is in
the spec at all, especially since it's only a SHOULD so any code that
deals with the header has to accept it both ways anyway.

Exactly.

I did glance add the routines in milter.c in the sendmail 8.13.4 source,
but that was late last night and i didn't try to properly understand the
semantics. I guess I'll just have to add insheader to Sendmail::Milter,
which doesn't seem like too big a deal.

Well, i guess the order is convenient if the message passes through
several spf validating hops, to be able to track progress easily
(remember the Received-SPF header would be imbedded in the Received
headers).
The 'rfc' mentions that clients can make information about the
validation process available, and if it does so it should use the
Received-SPF header as defined in the remainder of the text. So my
interpretation is that you can use the Received-SPF header, and if you
do so you should indeed put the header in order.

I freshened my patch to apply to the latest version. At this point it
would make more sense to have the values come back in the hash from
->results().

Things have gotten worse though! In 2005:

> The domain of this list v2.listbox.com needs 13 queries to return a
> softfail and pobox.com needs 23 queries to return neutral.

~/SPF $ perl test.pl spf-discuss@v2.listbox.com
fail
15 queries 0 cachehits

~/SPF $ perl test.pl spf-discuss@pobox.com
neutral
23 queries 0 cachehits


Is there not a limit of 10 queries at which point you're supposed to
reject the message with a permanent fail?

Cheers,

ds

Interesting. However there will hardly be another release of Mail::SPF::
Query. It's just grown too long of a grey beard.

Not sure where these extra 2 queries come from with your first test.
Perhaps v2.listbox.com's SPF record has changed?

> Is there not a limit of 10 queries at which point you're supposed to
> reject the message with a permanent fail?

Not exactly. There is a limit of 10 mechanisms that do DNS queries, and
for every "mx" (or "ptr") mechanism, at most 10 of the intermediate result
records (MX/PTR) may be looked up. In total, this leads to a number of
111 queries (including the initial SPF/TXT RR lookup) in the worst case.
