I have tried, with out success to do something similar before. The  
problem is that Postfix doesn't have any 'not' or 'and' rule

How does postfix receive your time critical mail? Is it possible to  
inject it using the sendmail binary? If so you can set a regex to only  
hold mail based on your server ID like thus:

/^Received:(.*)by your\.mail-server\.name \(Postfix\)/   HOLD

which will only put into the hold queue mail that comes in via SMTP.  
Injected mail produces headers like:

Received:by your.mail-server.com (Postfix, from userid 80) which  
doesn't match and therefore won't get held.

I don't know if this helps...
