FWIIW - the same sentiments where expressed when 'greylisting[1]' in SMTP came in vogue. For small relays (speaking just from personal experience and from the vantage of my own private tiny MTA's) that has however not been the case. Greylisting did dampen things significantly - and the effect lasts to this day. But agreed - I think it is important to deal with this issue differently that with the overload issue.
