We just drop (non-deliver) any message that's marked over our threshhold 
for spam; we use SpamAssassin, so it goes by total points (our threshhold 
is at 6 points), rather than percentage.  But our history of spam marking 
is extremely good, both in positives and negatives, and we figure we'd much 
rather have the rare non-delivery of a real message someone's posted than 
have any spam getting through to lists.  The few times someone's real 
message has gotten dropped, they've eventually written for support and 
we've helped them figure out why it was tagged, and made the proper 
adjustment either at our end or theirs.  It doesn't hurt to be educating 
people about spamminess anyway, since if they got tagged by us they're 
likely to get tagged by various list recipients' filters too, and this 
education improves their ultimate deliverability.
