This technology is much better than Spam filtering alone. Not only do you get the protection of MagicSpam, but since this occurs in the SMTP daemon (PRE-DATA) you also reduce backscatter problems that occur when your filters try to bounce messages to forged email addresses. By blocking instead of filtering you also reduce the overhead needed by your email filters during large spam attacks. As well you receive updates several times a day, to provide a more Zero Day prevention against new attackers, whether they be Spam or Dictionary Attacks. This edition is designed to integrate directly with Postfix servers and offers its own standalone interface - no need to mess around with apache configurations!
