The method behind the madness

[Daniel L. Miller]

I realize the developers and senior ops may be a bit irritated by some 
of my recent queries.  I plead ignorance - and a desire to improve.

I currently utilize ASSP as my primary filter.  In the past, I have 
heard that there is nothing ASSP does that cannot be done utilizing 
alternative tools - in many cases built-in Postfix functionality.  
Regardless of your opinion of ASSP, there is a particular feature which 
I cannot replicate - hence my questions.  That feature is auto-whitelisting.

The goal is simple - there are some people & businesses my company needs 
to correspond with no matter how strict my filter, and no matter how 
badly the remote site is configured.  Waiting to receive a message 
carrying critical business information is simply unacceptable - so I 
need an alternative.  ASSP provides me with one - by the simple act of a 
user sending a message to a remote, that address and/or domain is 
immediately whitelisted and immediately bypasses nearly all the spam 
filters (virus scans still occur).

Daily scanning of logfiles does not accomplish this.  Nor would even an 
hourly scan - and constant logfile scanning strikes me as inelegant.  If 
there is any method currently existing within Postfix to accomplish this 
goal please point me at it!  If not, I'd like to discuss possible means 
and methods for a future implementation.
