I have exim installed on my firewall to pass packets to my real mail
server on the inside. At least that is what I am triing to do. I am
not getting something and wonder if someone could this out.
Below is the exim.conf from the firewall computer.
Thanks in advance

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

# 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.

# The setting below causes Exim to do a reverse DNS lookup on all

# TRANSPORTS CONFIGURATION #

# Only one appropriate transport is called for each delivery. #
######################################################################
# This transport is used for local delivery to user mailboxes. On debian
# systems group mail is used so we can write to the /var/spool/mail
# directory. (The alternative, which most other unixes use, is to
deliver
# as the user's own group, into a sticky-bitted directory)

# or .forward files. It has a conventional name, since it is not
actually
# mentioned elsewhere in this configuration file. (A different name
*can*
# be specified via the "address_pipe_transport" option if you really
want
# to.) If the pipe generates any standard output, it is returned to the
sender
# of the message as a delivery error. Set return_fail_output instead if
you
# want this to happen only when the pipe fails to complete normally.

address_file:
driver = appendfile
# This transport is used for handling file addresses generated by alias
# or .forward files if the path ends in "/", which causes it to be
treated
# as a directory name rather than a file name. Each message is then
delivered
# to a unique file in the directory. If instead you want all such
deliveries to
# be in the "maildir" format that is used by some other mail software,
# uncomment the final option below. If this is done, the directory
specified
# in the .forward or alias file is the base maildir directory.
#
# Should you want to be able to specify either maildir or non-maildir
# directory-style deliveries, then you must set up yet another
transport,
# called address_directory2. This is used if the path ends in "//" so
should
# be the one used for maildir, as the double slash suggests another
level
# of directory. In the absence of address_directory2, paths ending in //
# are passed to address_directory.
