Maybe we can agree on a characterization of the costs and benefits of
repeating the explanation text?
I think part of the usefullness is that system administrators that are worried
about mail getting lost after their implementation of spf have the assurance
that at least, mail that gets rejected can be accompanied by a verbose message
with the reason. Is it really expensive to add 'dns of xxx.com said: ....' or
something, I think this was mentioned earlier on the list. Just add something
to the beginning to indicate where the message came from.
