No, I didn't copy/paste anything - I only quoted the email as it came to me (and hopefully removed all useless sections and kept only those usefull). > I am NOT asking about the advantages of smtp time rejection. > The second of my paragraphs above make it quite clear that I do that > myself on my own MXs but that I do it BEFORE receiving the message DATA. actually, there is a small difference between "receiving the message" and "receiving the message data", and maybe this is the reason why most people don't understand each other when talking about this issue. > I AM asking how you can scan an email through spamassassin without > receiving the bulk of the email and how, when the scanning is turned > off, it leads to a quadrupling of bandwidth used. I don't think that's quadrupling, but Yes, I agree this will cause MORE data sent across the net, and Yes, I agree that you must accept at least a part of the message data to verify if it's spam (the same about viruses). > > Especially if you would bounce the e-mail, you'll win this way... > > You should not bounce SPAM once you have accepted it for delivery.
