Bounce message example:

Hi. This is the qmail-send program at hostname.tld.
I tried to deliver a bounce message to this address, but the bounce bounced!

<user@sender_domain>: does not like recipient.
Remote host said: 550 user@sender_domain...User unknown
Giving up on

--- Below this line is the original bounce.
Return-Path: <>
Received: (qmail 30029 invoked for bounce); 23 Aug 2006 11:34:11 +0200
Date: 23 Aug 2006 11:34:11 +0200
From: MAILER-DAEMON@hostname.tld.
To: <user@sender_domain>:
Subject: failure notice

Hi. This is the qmail-send program at hostname.tld.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
This address no longer accepts mail.
This error message means that Qmail was not able to deliver the bounce message. In another words, the message was sent with the user@sender_domain email address in the "From" field to nonexistent mailbox user@destination_domain, and the message bounced back; however, user@sender_domain mailbox does not exist. It is not recommended to send bounce messages, but to instead reject mail for nonexistent users. This can be set for every domain on the Domain->Mail->Preferences page in the Parallels Plesk Panel CP.

To change this for multiple domains:
In PP 9 and earlier versions use the group operations feature.
In PP 10 and higher versions perform the changes in customer' service plans.
