We are using postfix as a front end mail server to relay the mail to
our master exchange server.

2 Questions

1st - how can i disable bounce messages. If the exchange server turns
an error and postfix wants to send a bounce message back to the
sender, i would like to disable this feature.

2nd - Can i disable bounce messages but log them on the server to
review the error messages my exchange server is sending.

Thanks in advance
