Almost but not quite. Bounces go to the SMTP envelope sender NOT, as 
Ian says, the address in the message From: header. MM normally puts the 
same value as the envelope sender into the message Sender: header but 
an MTA generating a bounce should only work off the envelope value and 
never off the message headers. In general you can have a different 
value in the Sender: header to the envelope From, which can ameliorate 
the behaviour of some versions of Outlook which upsets some users 
getting mail from lists; see:
