Are you using the spamassassin Vbounce plugin?  It serves a similar 
function as the watermarking.  In your case you would list your outgoing 
exchange servers in the

whitelist_bounce_relays

http://wiki.apache.org/spamassassin/VBounceRuleset

If you don't want to redirect the incoming bounces to a folder, as 
described in the wiki article, you can instead add points to them in 
spamassassin with something like

score BOUNCE_MESSAGE 5
