[Evolution] Problems with auto-pruning

[<dthacker9 cox net>]

Evolution 2.2.1   SuSe 9.3
Desired State:
All emails in mailbox "bb" (Big Brother Alarms") should be automatically deleted 5 days after I've received 
them.  They are stale and have no lasting value. 

What I've done:
Created a filter "If date received is before 5 days ago" then "delete" on "incoming"  

What's happening:
Messages are never deleted.

Is there a way to debug the operation of a filter to see what is going wrong?  Should it be set to "outgoing" 
instead of incoming?  Is there a setting that says "run when mail client is closed" or something like that?  

TIA
