RE: about 'invalid-domain-long-via-macro' test

Please forget mail previous question about 'invalid-domain-long-via-macro'.
The thing was that upper case macro wasn’t url escaped. 

 

Macro expand must results to the following :

%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25%25.bar 

and the first label is longer than 63 chars. So the test pass correctly.

I have a problem with the following test in the test suite :

 

invalid-domain-long-via-macro:

    description: >-

      target-name that is a valid domain-spec per RFC 4408 but an invalid

      domain name per RFC 1035 (long label) must be treated as non-existent.

    comment: >-

      A domain label longer than 63 characters that results from macro

      expansion in a mechanism target-name is valid domain-spec syntax (and
is

      not even subject to syntax checking after macro expansion), even
though

      a DNS query cannot be composed from it.  In analogy to 4.3/1 and
5/10/3,

      the mechanism should then be treated as a no-match.

    spec: [4.3/1, 5/10/3]

    helo: "%%%%%%%%%%%%%%%%%%%%%%"

    host: 1.2.3.4

    mailfrom: [email protected]

    result: fail

 

SPF record for t12.example.com is : v=spf1 a:%{H}.bar –all

 

Regarding the comment, I think that macro expansion of the ‘a’ mechanism
should result in a too long domain name label but when expanding ‘%{H}.bar’
the result is ‘%%%%%%%%%%%%%%%%%%%%%%.bar’ which does not contains label
longer than 63 chars …. ?

 

Can someone help ?
