This is true you did show me and i havent done it. But i extend my 
thanks again. :) Because, i dont want to run 2 instances of postfix 
again. I am too cautious about making changes to want to affect every 
single message to achieve it.

Another way is to set #smtpd_recipient_limit = 1 but this creates 
performance issues.

Anyway i wasnt trying to make a big deal out of it, only suggesting that 
it is something i would consider if was choosing the MTA for a new 
installation. If it was me starting again, i would choose Exim - based 
on my limited understanding of the features of these softwares.
