Yes - use add_header to add a 'X-New-Subject: [SPAM] $subject' header,
and replace Subject with X-New-Subject in a router. You'll have to do
this in the DATA acl.

Unless you're content to outsource the whole of your blocking policy
to perhaps multiple third-parties, it's sensible to have a whitelist
facility for just this kind of circumstance, which will bypass one or
more DNSBL checks for a list of sending IPs, or SPF-pass or
Domainkeys-pass sending domains.
