you are forgetting that users are stupid. As I've mentioned before I have to deal with abuse messages daily because users press "Junk" instead of "Delete" buttons. They don't understand the difference between "Junk" and "Trash" or they sort a regular mail response to junk because they don't like the answer they get. > The second is that it is impractical to ascertain whether a message is > spam or not during delivery time in all cases.

Why not get the message, give the sender a proper "please come again later", do OCR or whatever resource intensive scanning and allow or block the file based on a hash the next time it comes in? Worst thing I have seen were mails that got moved to spam out of my inbox where I had seen them before - and suddenly they were just gone. > Even without these things, often we aren't sure that something's spam, > so we rely on the folks always checking their email and clicking spam to > inform us on messages we've already received but haven't been looked at yet. > > Those also mean, there's no saying its rejected even if we put the > message in the spam folder. You guys probably don't have to deal with the "but where is my mail" - "did you check the spam folder" support tickets? If a mail gets properly rejected, the sender - who is the one that wants his mail to be delivered into the recipients inbox - knows something is wrong and can try again, contact the recipient in a different way or ask his postmaster to look into it (who has nice logs of the event). If you sort something into a spam folder, that most people don't bother to look into, mails just get lost.
