McAfee VirusScan On-Delivery Email Scanner log file size must be restricted and be configured to be at least 10MB.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
While logging is imperative to forensic analysis, logs could grow to the point of impacting disk space on the system. In order to avoid the risk of logs growing to the size of impacting the operating system, the log size will be restricted. If the data in the log file exceeds the file size set, the oldest 20 percent of the entries are deleted and new data is appended to the file so although the file size is restricted, it must also be large enough to retain forensic value.
