However, if your system is able to determine _during the SMTP session_ that the mail is unwanted (as spam or for some other reason), it can issue a 55X Reject error and refuse delivery, instead of accepting the mail and then having to make the poor choice between /dev/nulling the received mail and issuing an almost certainly inappropriate bounce message.
Yeah, big difference. If the spam is going through a relay, the relay will send the same bounce and the same person will get the bouncemessage.
