What i am trying to understand is :

if there is any way or method or command some how.. if we can see bounch back email.
suppose ..

if we sent an email to 1000 customer from, arround 200 email will bounch back to us as they are not valid email address

when email bounched back it should come back to inbox.

but from exim is there any way to forward thsoe bounch back email  from to another account so that we can just ahve a look .

* We can check infbox. but this inbox does not exist, its a Alias of another inbox , and we cant go and ask those user about bounch back.
so we need to get an option to foward any bounch back email comming to email address should be forward to anotehr email account

or some other way ..

bottom line is, we just interested on bounch back email on

thanks for your advise.

    Bounces are delivery notification.
    By definition those have a from address <>  (empty address).

    So you can create a router that catches all mails from <> to <> and forward them to a different mailbox. (I might have made some errors below, but it should be along the same lines)
    The router should be one of the first used.

         driver = redirect
         condition = ${if {and {match {$sender} {<>}} {match {$receipient} {}}}
         data =
         file_transport = address_file
         pipe_transport = address_pipe
