Issue/Introduction

Symantec Mail Security for Microsoft Exchange is installed on an Exchange server. The Premium AntiSpam feature, the AntiSpam Heuristics engine, or Real-time Blacklists have been enabled. Spam, is still received and the spam statistics show zero spam detections.

Email is through a POP3 server.

Resolution

Symantec Premium AntiSpam and the AntiSpam Heuristic engine scans only SMTP traffic.
