Anti spam appliances evolved to address this problem. Basically the function of any anti spam software is to identify and isolate the malicious, unwanted email from rest. This software is coded in such way that all unwanted emails are collected in a spam folder and you can delete all such emails after confirming yourself that they are spam.
