FIltering out Internal Mail Logging

[<frank.hodits () skipjack com>]

I am running Snort 2.0.  We have it running in IDS mode.  The logs keep getting full of internal traffic.  I am a 
rookie at creating rules and need some advice.  Are there default rules that I can download that have the most recent 
security threats?  
 
Thanks,
Frank
