I don't see anything in your link referring to mailer-daemon.
I don't know of any way to have exim set up custom individual mailer-daemon return addresses. A search of the exim-users mailing list finds this, from Dr Hazel (author of exim) written back in 2004:
You probably need this Wish List item to be implemented:
------------------------------------------------------------------------------
(158) 29-Jun-2000 S Configure "From" in bounces

Cf Reply-To.
------------------------------------------------------------------------------
Meanwhile, try return_path setting on transport (off the top of my head;
no time to spend on this).
The current exim wish list file, found
here, says simply:
The Exim Wish List has been imported into the Exim Bugzilla, which is where all new wishes should be added. This file is no longer maintained.
The current bugzilla item shows this hasn't yet been implemented; look
here for details. Note it's no longer wishlist item 158, but rather bug 149.
Or in other words, no, it can't be done unless Dr Hazel's suggestion works. I haven't tried it.
Of course it's a wishlist item. You can certainly add it to Exim yourself, and the community will thank you for it
.
That all said, my response to the thread in the exim-users list, back in 2004, said this:
We're in the same situation.
So we've set the canonical name of our mailserver to a relatively
anonymous domain name that can't easily be traced to us. We use the
same anonymous domain name for nameservers our resellers use as well.
And the website is anonymous as well. The whois is in my own name and
address, and phone number, not the business information.
Now, however, the whois is an anonymous proxy domains registration.
