Hi Paul,
...
That matches https://kb.isc.org/docs/aa-00356 The RFC referenced in
that article is RFC 4408 instead of RFC 7208.
the concatenation of <character-strings> on 255-octet boundaries has
never been specified in a DNS RFC, and if the DKIM and SPF
specifications require this, they are legislating from the bench.
RFC 1035 Domain Implementation and Specification November 1987
<character-string> is expressed in one or two ways: as a contiguous set
of characters without interior spaces, or as a string beginning with a "
and ending with a ". Inside a " delimited string any character can
occur, except for a " itself, which must be quoted using \ (back slash).
Because these files are text files several special encodings are
necessary to allow arbitrary data to be loaded. In particular:
...
( ) Parentheses are used to group data that crosses a line
boundary. In effect, line terminations are not
recognized within parentheses.
...
Mockapetris [Page 35]
i think this means i won't be using SPF or DKIM, nor exchanging e-mail
with anyone who requires that i do so. piling kluge on kluge because the
right person wasn't in the right room 15 years ago is no way to build a
railroad i'm willing to ride on.
