MCP is basically a second spamassassin run. You can just do the same 
during the normal SA run. Stephen pointed at some caveats. There is an SA 
plugin for simple whitelisting by subject, it just needs to be enabled in 
the *.pre file in /etc/mail/spamassassin. But this will whitelist for all 
I think the better approach is to whitelist the assumed senders or give 
that user a special alias that doesn't get filtered and that he can hand 
out to those where he thinks there might be delivery problems.
