I am not really familiar with how UNIX mail works behind the scenes, but I have used it for years as just a user. 

Is there any way to do any mail filtering with unixmail?  I see that including procmail is in the "To Do" list.  Has anybody gotten procmail working anyway?  Is there any other way to do email filtering with unixmail, or will I be forced to manually delete all of my spam?
