greylisting does not necessarily catch incorrectly implemented SMTP but 
basicly catch any source not seen before with a correct greeting unless it is 
whitelisted

then, spam is not necessarily incorrectly implemented SMTP and can be an 
absolute correct email message (within SMTP specs) which then btw is rejected

so the question is, if this is a correct way to handle it, rejecting I mean

also a point to think about, most complains about spam talk about bandwidth 
consumption, by asking for resend later you certainly increase bandwidth 
consumption and resources on both sides
