Here is exim.conf I use that is tailored for mailman. I got this from
the exim mail list. It's brilliant! Everything is automatic.
(Ignore the parts that are specific to my site)

# Runtime configuration file for Exim #
######################################################################
# This is a default configuration file which will operate correctly in
# uncomplicated installations. Please see the manual for a complete list
# of all the runtime configuration options that can be included in a
# configuration file. There are many more than are mentioned here. The
# manual is in the file doc/spec.txt in the Exim distribution as a plain
# ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are available
# from the Exim ftp sites. The manual is also online via the Exim web sites.
# This file is divided into several parts, all but the last of which are
# terminated by a line containing the word "end". The parts must appear
# in the correct order, and all must be present (even if some of them are
# in fact empty). Blank lines, and lines starting with # are ignored.

# MAIN CONFIGURATION SETTINGS #
######################################################################
# Specify your host's canonical name here. This should normally be the fully
# qualified "official" name of your host. If this option is not set, the
# uname() function is called to obtain the name.
# primary_hostname =
# Specify the domain you want to be added to all unqualified addresses
# here. An unqualified address is one that does not contain an "@" character
# followed by a domain. For example, "caesar at rome.ex" is a fully qualified
# address, but the string "caesar" (i.e. just a login name) is an unqualified
# email address. Unqualified addresses are accepted only from local callers by
# default. See the receiver_unqualified_{hosts,nets} options if you want
# to permit unqualified addresses from remote sources. If this option is
# not set, the primary_hostname value is used for qualification.
qualify_domain = hns.com
# If you want unqualified recipient addresses to be qualified with a different
# domain to unqualified sender addresses, specify the recipient domain here.
# If this option is not set, the qualify_domain value is used.
# qualify_recipient =
# Specify your local domains as a colon-separated list here. If this option
# is not set (i.e. not mentioned in the configuration file), the
# qualify_recipient value is used as the only local domain. If you do not want
# to do any local deliveries, uncomment the following line, but do not supply
# any data for it. This sets local_domains to an empty string, which is not
# the same as not mentioning it at all. An empty string specifies that there
# are no local domains; not setting it at all causes the default value (the
# setting of qualify_recipient) to be used.
local_domains_include_host
local_domains = hns.com:localhost:localhost.hns.com
# If you want to accept mail addressed to your host's literal IP address, for
# example, mail addressed to "user@[111.111.111.111]", then uncomment the
# following line, or supply the literal domain(s) as part of "local_domains"
# above. You also need to comment "forbid_domain_literals" below. This is not
# recommended for today's Internet.
# local_domains_include_host_literals
# The following line prevents Exim from recognizing addresses of the form
# "user@[111.111.111.111]" that is, with a "domain literal" (an IP address)
# instead of a named domain. The RFCs still require this form, but it makes
# little sense to permit mail to be sent to specific hosts by their IP address
# in the modern Internet, and this ancient format has been used by those
# seeking to abuse hosts by using them for unwanted relaying. If you really
# do want to support domain literals, remove the following line, and see
# also the "domain_literal" router below.
forbid_domain_literals
# No local deliveries will ever be run under the uids of these users (a colon-
# separated list). An attempt to do so gets changed so that it runs under the
# uid of "nobody" instead. This is a paranoic safety catch. Note the default
# setting means you cannot deliver mail addressed to root as if it were a
# normal user. This isn't usually a problem, as most sites have an alias for
# root that redirects such mail to a human administrator.
never_users = root
# The use of your host as a mail relay by any host, including the local host
# calling its own SMTP port, is locked out by default. If you want to permit
# relaying from the local host, you should set
#
host_accept_relay = localhost
#
# If you want to permit relaying through your host from certain hosts or IP
# networks, you need to set the option appropriately, for example
#
# host_accept_relay = my.friends.host : 131.111.0.0/16
#
# If you are an MX backup or gateway of some kind for some domains, you must
# set relay_domains to match those domains. This will allow any host to
# relay through your host to those domains.
#
# See the section of the manual entitled "Control of relaying" for more
# information.
# The setting below causes Exim to do a reverse DNS lookup on all incoming
# IP calls, in order to get the true host name. If you feel this is too
# expensive, you can specify the networks for which a lookup is done, or
# remove the setting entirely.
host_lookup = 0.0.0.0/0
# By default, Exim expects all envelope addresses to be fully qualified, that
# is, they must contain both a local part and a domain. If you want to accept
# unqualified addresses (just a local part) from certain hosts, you can specify
# these hosts by setting one or both of
#
# receiver_unqualified_hosts =
# sender_unqualified_hosts =
#
# to control sender and receiver addresses, respectively. When this is done,
# unqualified addresses are qualified using the settings of qualify_domain
# and/or qualify_recipient (see above).
# By default, Exim does not make any checks, other than syntactic ones, on
# incoming addresses during the SMTP dialogue. This reduces delays in SMTP
# transactions, but it does mean that you might accept messages with unknown
# recipients, and/or bad senders.
# Uncomment this line if you want incoming recipient addresses to be verified
# during the SMTP dialogue. Unknown recipients are then rejected at this stage,
# and the generation of a failure message is the job of the sending host.
# receiver_verify
# Uncomment this line if you want incoming sender addresses (return-paths) to
# be verified during the SMTP dialogue. Verification can normally only check
# that the domain exists.
# sender_verify
# Exim contains support for the Realtime Blocking List (RBL) that is being
# maintained as part of the DNS. See http://maps.vix.com/rbl/ for background.
# Uncommenting the first line below will make Exim reject mail from any
# host whose IP address is blacklisted in the RBL at maps.vix.com. Some
# others have followed the RBL lead and have produced other lists: DUL is
# a list of dial-up addresses, and ORBS is a list of open relay systems. The
# second line below checks all three lists.
# rbl_domains = rbl.maps.vix.com
# rbl_domains = rbl.maps.vix.com:dul.maps.vix.com:relays.orbs.org
# If you want Exim to support the "percent hack" for all your local domains,
# uncomment the following line. This is the feature by which mail addressed
# to x%y at z (where z is one of your local domains) is locally rerouted to
# x at y and sent on. Otherwise x%y is treated as an ordinary local part.
# percent_hack_domains = *

# Local addresses are those with a domain that matches some item in the

# routers because of a "self=local" setting (not used in this configuration).
# This director handles aliasing using a traditional /etc/aliases file.
# If any of your aliases expand to pipes or files, you will need to set
# up a user and a group for these deliveries to run under. You can do
# this by uncommenting the "user" option below (changing the user name
# as appropriate) and adding a "group" option if necessary. Alternatively, you
# can specify "user" on the transports that are used. Note that those
# listed below are the same as are used for .forward files; you might want
# to set up different ones for pipe and file deliveries from aliases.

# If you want it also to allow mail filtering when a forward file
# starts with the string "# Exim filter", uncomment the "filter" option.
# The no_verify setting means that this director will be skipped when
# verifying addresses if sender_verify or receiver_verify is set (though
# they are not set by default). Similarly, no_expn means that this director
# will be skipped if smtp_expn_hosts is set to allow any hosts to use the
# EXPN command.
# The check_ancestor option means that if the forward file generates an
# address that is an ancestor of the current one, the current one gets
# passed on instead. This covers the case where A is aliased to B and B
# has a .forward file pointing to A.
# The three transports specified at the end are those that are used when
# forwarding generates a direct delivery to a file, or to a pipe, or sets
# up an auto-reply, respectively.
