Hi,
I'm having here a mail that scores as DKIM_INVALID. I tried sending the same
mail to gmail for example and it tells me that DKIM is valid. Now I put it
through "spamassassin -D" and I am even more baffled because the debug seems to
say that DKIM is valid but then scores as INVALID.
Any idea why this could be?
