How can I customize the output of undeliverable mail? For example, mails sent to the wrong email address will return an error. I want to translate this error into a different language. Is it possible?

Hey there! While this is an older thread, the process does remain the same for creating a custom bounce template:
forums.cpanel.net
Can you try that and see if that accomplishes what you're looking for?
Customize Exim bounce messages
Hello. Most of our email users can't understand english, so it could be very good for us to translate all bounce messages sent by Exim, or to send them in local language and english. Is there any way to do it in WHM, and to avoid reconfiguration after every cPanel upgrade? Thank you in...

Hello, im on the same boat, im trying to customize the bounce messages, i also read the old thread and the exim documentation, however is no 100% clear to me.
I see that there are some "variables":
bounce_message_text
bounce_message_file
$bounce_recipient
$bounce_return_size_limit
return_size_limit
warn_message_file
There is also a template (that is called as file)
my doubts are the following :
1) There is no mention of where the template file needs to be saved
2) There is no mention of message/templates variations depending on the reason for the bounce (there are many variations), bounced by sended verification failed, bounced by dkim failed, bounced by user do no exists, bounced by mailbox full, etc..
My need in this moment is to custom the bounce messages by sender verify failed and dkim failed, is the most bounce reasons that is affecting my users but all the senders (and my clients) blame the server that is rejecting the messages as they dont understand english or dont read the bounce message because it seems too generic, so i need to create a custom bounce message that says that the problem is the miss-configuration or bad configuration of they domain and pass the bounce message to they system/domain administrator, where can i customize the bounce message for that specific bounse reasons?

I'm interested in this as well. I'm reading the linked and Exim documentation, and I'm not sure cPanel is using the same default messages for bounce_message_file.
How can I see this template that Exim is using?

You can do this following these instructions through the advanced editor:

That's the link I followed, but the text that appears in that document doesn't seem to be EXACTLY the one that cPanel is sending. That's why I'd like to see the original text in the server, so I can copy it verbatim and translate it. Not sure if I'm explaining myself well here? 
I don't think there is a specific template - Exim generates the bounce on the fly according to all the conditions met here in section 22:
It would also depend on system/domain filters as well. Even the guide I linked previously at 50. Customizing bounce and warning messages says this:
"The text of these messages is built into the code of Exim, but it is possible to change it, either by adding a single string, or by replacing each of the paragraphs by text supplied in a file."
When you perform the customization option, that overrides the Exim defaults to use that information.
