Do not reject mail after one of your SMTP servers (or that of your MSP, ISP, ...) has accepted it. reject during the smtp transaction, when the smtp client is a "stranger". Otherwise, tag and (deliver|quarantine|discard|...). if you bounce spam, the bounce will go to innocent victims. This is called backscatter and you'll find a lot of infos about it. suffice it to say that it is considered abusive. note that if your bounce contains malware, phishing or nigerian scam text, then you are participating to a criminal activity. you may say it's not voluntary or plead ignorance. but now you know.
