Recommendation here is an /etc/aliases entry to an mbox file...

... _but_ poster seconds your comments that Debian's default Exim
configuration doesn't allow delivery to files in /etc/aliases -- which 
I guess on reflection is true.  I don't make entries deliver to _files_,
but rather to other users, which is to say, processing the mail back
through the mail chain and its LDA (procmail).

So, commenter Roger Lynn says that the real solution is to add the correct
Exim4 router + transport to /var/lib/mailman/bin/postfix-to-mailman.py
for handling mail-loop, and he opened a bug requesting someone do that.

Except -- haha! -- in the end Roger Lynn said 'Screw it' and just did
mail-loop: root
...in /etc/aliases.
