is rumored to have said:
I'm beginning to think that DKIM headers might be
getting added just to improve spam detection scores.
Perhaps I'm getting too cynical. :-)
That would not be very effective.
For example: in Apache SpamAssassin, the presence of a valid DKIM
signature has a net zero score. If it is valid and aligns with both the
envelope sender and the From header address, it can net only -0.2 in a
scoring system with a standard spam threshold of 5.0. That's not quite a
meaningless benefit, but it is not substantial.
