poppycock 
I've been using SPF since its very VERY early days since befopre it was
even mainstream, never had a problem with mailing lists, not even the
antiquated majordomo or that shitty qmail thing, the ONLY SPF "From"
checking that has screwed up mailing lists is mickey$ofts piss poor
attempt at going it their own with their own SPF, yeah that spf2.0
garbage, and DKIM doesnt play nice with lists either, waste of time. 

As much a it pains me to agree with him, Harry is right, you're full of
shit.
