I think I understand what you're getting at, but it seems like an extra layer 
of complexity that might not fit in amongst what I already have.  Ideally, 
incoming messages would be sent to the junk folder instead of the inbox on 
any occasion where they have the relevant spam header.  Unless I can either 
configure getmail to do what you're describing for procmail, or I configure 
procmail to do everything that getmail is doing now plus what you describe, 
I'm not sure that procmail would be able to figure out which messages to 
process in any efficient way.

Does this mean I'll have to resort to a more complicated system like the ones 
Mark Street described?

Then again, since I have no prior experience with procmail, I may be 
completely misreading your suggestion.
