Well, that problem might well be solved by 1.6d, which fixed a problem with the "Ack=" keyword being ignored on "Mail-via= DISTRIBUTE" lists. But then if the list is a peered redistribution and the sender has requested mail acknowledgements, it works as designed. By the way, the only reason why 1.6d isn't being released this week (it originally supposed to go out on the 11th) is that I got all these LINKFAIL messages telling me about all sorts of computers that would be down during Christmas, and remembered that we too would be going down on friday until the 2nd of january. That is, if the 3380 bearings that our user community demanded that we do not change decide not to die after these 10 days of interrupt in a building whose temperature will quickly reach its yearly minimum after the shutdown.
