I completely agree, indeed it does not.. which is why we have now dropped doing secondary mx for this domain. Anyway.. thanks to all who responded on and off list.. gave me a few good ideas to tinker with.. Probably the most notable thing from this is the technical level with which spammers are now employing such a distributed network of spamming zombie type systems in a very directed manner.. and I always pictured them as drooling slobs that stare at blinking lights.. ;) Randy Bush wrote:

You want to keep a list of valid accounts on the secondary so you can refuse mail for non-existing accounts on the secondary too.
anyway, as they say, that does not scale
