This thread might be helpful for you, as i dont think there is a way to change the default Reply-To address in postfix, but if you are sending emails from other clients, like php or mailx,then you can change the Return path.

The bounce address is taken from the SMTP envelope from address provided by the client. This is usually the same as the RFC2822 from address in the message header, but it doesn't have to be. For example, in the following message submission the bounce address will be "" and not "":

> EHLO mamma.local
< 250
< 250 OK
< 250 OK
< 354 End data with <CR><LF>.<CR><LF>
> From:
> To:
> ...
> .
< 250 OK: queued as 12345

To change it you need to reconfigure the mail user agent sending the message in the first place, and not the mail transfer agent (Postfix in this case). How you do that depends on what is sending the messages.
