If a MTA thinks an incoming mail is spam, it can reject it with a 5xx. If it doesn't - i.e., accepts it for delivery - then it must deliver or bounce (indeed, I think it's required to do that by relevant RFCs). >I would assume that hotmail (and the others) have user options that >say 'delete spam', so they don't have to look at it in their spam >folder.

Yes, I think what is happening is that hotmail or others mark the mail as spam and place it somewhere, users don't realize it and say "I didn't receive it". Actually it is delivered, and users can read it if they like and know how.
