In addition, Barry was talking about concocting a unique identifier from the Date field and Message-ID. I'm not a big fan of this idea, because the date field comes from the mail user agent and is often wildly corrupt; e;g; coming from 100 years in the future.
Oh--I was assuming the Date to which he was referring was the current timestamp at which mailman was processing the message. I was going to say that this guarantees uniqueness, but I guess there are parallel mailman implementations where more than one machine/processor are all serving the same list, and then two different machines/processors might wind up with identical timestamps while processing two different messages.
