Following my previous question about the configuration file, my current
configuration file is given below:


######################################################################
#                  Runtime configuration file for Exim               #
######################################################################

primary_hostname = agni.unl.ac.uk

# qualify_recipient =

#local_domains = agni.unl.ac.uk:unl.ac.uk

# local_domains_include_host_literals

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 = 127.0.0.1/8
relay_domains = tara.unl.ac.uk
no_relay_domains_include_local_mx
no_relay_match_host_or_sender

#
# 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@z (where z is one of your local domains) is locally rerouted to
# x@y and sent on. Otherwise x%y is treated as an ordinary local part.

# percent_hack_domains = *

#     Only one appropriate transport is called for each delivery.    #
######################################################################


# A transport is used only when referenced from a director or a router that
# successfully handles an address.



# This transport is used for local delivery to user mailboxes in traditional
# BSD mailbox format. By default it will be run under the uid and gid of the
# local user, and requires the sticky bit to be set on the /var/mail directory.
# Some systems use the alternative approach of running mail deliveries under a
# particular group instead of using the sticky bit. The commented options below
# show how this can be done.

local_mbx:
driver = appendfile
file = /var/mail/${local_part}
delivery_date_add
envelope_to_add
return_path_add
group = mail
mode = 0660
mbx_format
prefix =
suffix =
require_files = +${home}/.wantmbx



# This transport is used for handling pipe deliveries generated by alias
# or .forward files. 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 of return_output if you want this to happen only when the pipe fails
# to complete normally. You can set different transports for aliases and
# forwards if you want to - see the references to address_pipe in the directors
# section below.

address_pipe:
driver = pipe
return_output


# This transport is used for handling deliveries directly to files that are
# generated by aliassing or forwarding.

address_file:
driver = appendfile
delivery_date_add
envelope_to_add
return_path_add


# This transport is used for handling autoreplies generated by the filtering
# option of the forwardfile director.

address_reply:
driver = autoreply


end



######################################################################
#                      DIRECTORS CONFIGURATION                       #
#             Specifies how local addresses are handled              #
######################################################################
#                          ORDER DOES MATTER                         #
#   A local address is passed to each in turn until it is accepted.  #
######################################################################


# Local addresses are those with a domain that matches some item in the
# "local_domains" setting above, or those which are passed back from 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.

system_aliases:
driver = aliasfile
file = /etc/aliases
search_type = lsearch
file_transport = address_file
pipe_transport = address_pipe


# This director handles forwarding using traditional .forward files.
# 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.

userforward:
driver = forwardfile
file = .forward
no_verify
no_expn
check_ancestor
# filter
file_transport = address_file
pipe_transport = address_pipe
reply_transport = address_reply


# This director matches local user mailboxes.

local_mbx:
driver = localuser
transport = local_mbx

Can anybody spot any obvious error?
