Are spammers really going to suffer because you're reducing your 
reliability?  Somehow, I doubt it.

I consider this behavior a gift.  If you're using decent bayesian 
filtering, it won't take long before you develop a strong (but flexible) 
distaste for messages relayed through your secondary. Problem solved.

I'm *delighted* spammers are willing to do the difficult work of helping 
me identify bogus messages.  You really want to change that?

Instead of getting rid of your secondary MX, it might make more sense to 
think about getting rid of spam assassin.  I've had vastly better (more 
accurate, less costly) results with CRM114.

YMMV, of course.
