OK I must be a rock. I have tried this quite a few times and I can not
get it working. What I really want to do is have exim installed on a
linux computer setup as a router (
www.linuxrouter.org). This is
connected to the internet and my local network (172.16.0.0).
I have a machine on the inside (172.16.0.32) that I want to actually
recieve and do the pop/smtp thing for the users. I can't figure out if
my ipfwadm rules are blocking traffic or my exim configure is dorked.
below is my configure.
Thanks in advance for any help.

######################################################################
# 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.
# 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@???" 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 =
# 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 =
# If you want to accept mail addressed to your host's literal IP address,
for
# example, mail addressed to "user@???", then uncomment the

"local_domains"
# above.

# 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 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.

# The setting below locks out the use of your host as a mail relay by any
# other host. If you want to permit relaying through your host from
certain

the

# See the section of the manual entitled "Control of relaying" for more
info.

to

deliveries to
