That *could* happen.  In practice, I've not seen it.  In any event, it would
happen only once for a given sending MTA.  If that is the price I have to
pay for reducing incoming SPAM by over 80% it is well worth it.  In a short
period of time all of those MTA's will long delays will be cached.

I bet those people that fret over this also have their user agents set to
poll for new mail every minute.

That is what the cache does....without any human intervention.
