Thanks. This was one of the issues I had brought in the issues list.
I think what is may be important is what to do when a header is different
from a possible copy in the z= list.
I.e., for a mailing server that may alter the subject line to add the
[mailinglist_name] subject tag.
Example: This might be the correction.
// Hash Headers
hash = empty;
for each hdr in (dkim_h_list) do
s = mail_headers[hdr];
sz = dkim_z_list[hdr]; // see is copy is available
if (s != sz) {
WHAT? INVALID? Should they be the same?
What can cause this? Mailing list?
}
if (s == "") s = sz; // correction
if (s != "")
hash += hash_string(s)
else
WHAT? INVALID?
end for
Make sense?
