Sorry about the bizarre phrasing. This is what I had in mind when I mentioned ToUsenet.
I think the approach below would be better.
As indicated in another reply, another approach would be to have gate_news run the message through the spam checks directly before queueing it.
As Brad points out, though, those checks are already done by the MTA, and in fact may not even be implementable outside the MTA (if they're implemented as milters, for example).
In general, there really is a tradeoff here. Although Skip seems happy enough, as I guess SpamBayes catches most (all?) of the spam his system catches.
