Spam passing as "System Message"

I am recently seeing a lot of spam coming through that is shown in the log as class: "System Message" and seems to be unfiltered as a result. Is there something I can do to filter these?

@Steve Yester: Log entries with "System message" class indicates events which are not closely related to emails (e.g., the ORF Service has been started successfully), so I'm not sure I understand the question... What is the exact message for these entires (in the last, "Message" column in the Log Viewer)?

@mark rosenbaum: According to the full log message you posted in this thread:

http://www.vamsoft.com/forum/topic/show/Block-chinese-characters_/4

this only indicates that a recipient address of an outgoing email was added to the Auto Sender Whitelist database. Since this does not involve any actions related to filtering (only a database operation), ORF logs these with "System" class.
