[G4] Training Junk Mail Filters

[Kevin Willis]

I am trying to train "Mail" on my G4 running OS 10.3.7 to filter out 
all the warning messages from the various LEM lists I subscribe to.  
Can some one explain exactly how to do it?  I have been labeling all 
the warning messages as junk.  Will "Mail" eventually learn that all 
the warning messages are junk and eventually filter them out of my in 
box?  Or, are there more steps I need to take to perfect it?

Thanks,

Kevin
