Exim bounce setup

Bdzzld
Hi, We've setup Exim (for security reasons) to only bounce e-mail headers (and not the full e-mail) in case of an incorrect recipient's e-mail address, by adding the following to the Exim configuration:
bounce_return_message = false bounce_return_body = false
This works without problems. We'd also like to setup a message to let the receiver know about this and have found the following in another server's setup bounce : X-Exim-DSN-Information: Due to administrative limits only headers are returned
The question: How can the latter be added to our bounces? Thanks.

    @cPanelMichael: That thread is focussed on autoresponders, while mine is focussed on a bounce message someone receives when an e-mail address is not valid. Hereby a sample of such an e-mail: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: email@email.ext[/EMAIL] (ultimately generated from email2@email2.ext[/EMAIL]) host mx4.email.ext [111.222.333.444] SMTP error from remote mail server after RCPT TO:: 552 5.2.2 quota exceeded Reporting-MTA: dns; server.domain.ext Action: failed Final-Recipient: rfc822;email@email.ext Status: 5.0.0 Remote-MTA: dns; mx4.email.ext Diagnostic-Code: smtp; 552 5.2.2 quota exceeded Return-path: Received: from sub.dynamic.provder.ext ([222.333.444.555]:49244 helo=pc.domain.ext) by server.domain.ext with esmtpsa (TLSv1:DHE-RSA-AES256-SHA:256) (Exim 4.89_1) (envelope-from ) id 1eU5Tb-0007oI-Ib for email@email2.ext[/EMAIL]; Wed, 27 Dec 2017 07:46:08 +0100 X-Priority: 2 (High) Date: Wed, 27 Dec 2017 07:46:07 +0100 To: "A.N.

    I'd like to have the last line added to our bounces as well. How do I do this? Thanks.

    Hello, The thread originates with a question about autoresponders, but then goes into information about Delivery Status Notifications with Exim (DSN), which is what you need to enable to include that information in the bounce message. Thank you.

    @cPanelMichael So, if I understand correctly, I've to add the following line :
    dsn_advertise_hosts = *
    to the file /etc/exim.conf.local under the @config@ section in order to have the header : X-Exim-DSN-Information: Due to administrative limits only headers are returned
    added to our bounces?

    Hello, You'd need to enable DSN first before you could include DSN information in the message headers, so the instructions in that thread are the the first step to take. Additionally, I suggest reviewing the Exim documentation for more information about "dsn_advertise_hosts" at: 14. Main configuration That said, as far as including that information in the message header, I don't believe that happens automatically. Note that this is a custom Exim configuration, so it's not something we offer support for. You may want to consult with the Exim user's mailing list or a system administrator for help customizing Exim to include that in the header: Exim-users Info Page System Administration Services | cPanel Forums Thank you.
