first of all, i'll start with a pet-hate: the travesty of split-file
configuration and Pkg-exim4.
secondly, I presume you've config'd mm_cfg.py to "MTA = None", created
the site-list, and started the Mailman runners?

This is possibly where obscurating your mail domains is an hinderance.
Is example.com listed in your exim config as a mailman domain: i'd
suggest just using *one* guide, and the Exim one is probably one of
the saner approaches out there (it's what I'd use).
Are you using the "exim4-daemon-heavy", too?
Remember, the order of routers is significant, so ensure the Mailman
router's in the right place in your config file.
Is the transport set to run with the appropriate user/group for
Mailman (normally, if you've used Debian packages, this will be

That depends on how you've set things up: if you've used Nigel's &c
guide, per exim.org, then no: it's all handled elsewhere in the
It's probably worth running something like
"exim -C /etc/exim/configure -bV"
("/etc/exim4/exim4.conf" may be more appropriate for you: I've been
known to build my own exims on debian boxes.)
to check your config files are in working order: and if you've not
HUP'd the exim daemon since fiddling with the config, that too.
If you're using a monolithic exim4.conf/configure file, shove it
somewhere, and I'll have a look at it for you.
