Hmmn. I suppose that if I wanted to set up a mail system to maximize
the chance that my mail would fall afoul of well established
anti-abuse metrics and get thrown on the floor, that'd be a good plan.
Please cite these "well established anti-abuse metrics" because they
should not be accepted as valid without question.
If you refuse to do so, it should be assumed that they are either not
well established or that they are not valid. Or perhaps, they are
themselves a form of abuse.
