How do you know what is personal and what is commercial?  I assume you 
can detect what is listmail by looking at the message or certain other 
factors....

Basically, you're looking to set up special postfix transport maps.  A 
couple of examples are discussed at 
<http://www.postfix.org/QSHAPE_README.html>, but I'm sure the 
documentation, the FAQ, and the archives of the postfix-users mailing 
list would have a lot more examples that might be more useful to you.
