Sure.  Let me mention two things before you take my example to heart too
much...  First, I migrated this from exim 3 to exim 4 so maybe there is a
better way.  Also, the Debian exim 4 packages distribute the configuration
file into bits in a directory structure - for good reasons, I'm sure.  (For
example, if the mailmain maintainer gets on board then mailman could simply
install it's own bits in the to configuration heirarchy and it should work
out of the box.)  However, I had a fairly customized exim setup and needed
it working quickly, so I went the "monolothic file" route and have a
"/etc/exim4/exim4.conf"....  Having said all of that, here you go -
anything in "[]" is my comments to you and not actually in the file.

[beginning of /etc/exim/exim4.conf]
# All macro definitions have been gathered here to ensure
# they precede any references to them.

MAILMAN_HOME=/var/lib/mailman
MAILMAN_WRAP=MAILMAN_HOME/mail/wrapper
MAILMAN_UID=mail
MAILMAN_GID=list

[ that's it for the exim4.conf file ]

In addition to the exim4.conf file, then you have to setup lists.  It's
been a while since I've down this, but I recall it being straightforward
simply following the docs.

Take care,
