Just to prevent misunderstandings, I don't think my Qmail setup does anything "weird" at all. Just that if you consciously want to score according to the MTA used, that you can. The only weird thing about a Qmail installation adapted to today (backscatter protection, DKIM, standard Qmail patches) is that not many people are using it.
