Well, the only way to reject an email because it is considered spam is after complete reception; the scanning is surely done later. It is simply a «bad thing» to bounce back spam.
Not always. Sometimes you want to reject messages as spam based on certain well-known (at least for a small timeframe) source IPs, FROM or RCPT-TO addresses (for example to reduce the load on the mailserver).
