The problem is the very last body line "--=_related
004DF4F0C1257428_=--". This line appears truncated in the canonical
message dump as "--=", what causes the body hash verification to fail.
The reason for the truncation, I believe, is the l= tag of the signature.
The following reflectors produce the same wrong result as shown above:
test(_at_)dkimtest(_dot_)jason(_dot_)long(_dot_)name
verifier-feedback(_at_)port25(_dot_)com
mail(_at_)testing(_dot_)dkim(_dot_)org
It seems to be a problem in the under-laying libdkim.
The verifier at test(_at_)dkimtest(_dot_)jason(_dot_)long(_dot_)name does not
use libdkim, it is
an independent implementation.
Oddly enough, in my tests, the truncation is occurring at a slightly
different spot. So there's something fishy going on, I'm not sure what.
