LinuxQuestions.org - exim not sending external mail

sorry about the shotty details of the first post. I am at work, so I have to do this in between fires. I'm at lunch now so I can give a bit more detail.

Checking the /var/log/exim/mainlog I get this error message and a few others:

refused relay (host) to <externaladdress.com> from <internaladress.com> H=(Aaron)

[192.168.0.107] (failed to find host name from IP address)

I don't have DNS set up on this network. When I last set exim up at my old home (about 18 months ago) I never set dns up their and could send and recieve like crazy.

My exim.conf file, I'v changed the domain to xxxx.com to protect privacy.

# Specify the domain you want to be added to all unqualified addresses

# 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.

# in the DNS as an MX for.

relay_domains_include_local_mx = true

# 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.

# for more info.

# If this option is set, then any process that is running as one of the

# Some operating systems use the "gecos" field in the system password file
# to hold other information in addition to users' real names. Exim looks up
# this field when it is creating "sender" and "from" headers. If these options
# are set, exim uses "gecos_pattern" to parse the gecos field, and then
# expands "gecos_name" as the user's name. $1 etc refer to sub-fields matched

# This sets the maximum number of messages that will be accepted in one
# connection and immediately delivered. If one connection sends more

# but is too low on dialup SMTP systems, which often have many more mails
# queued for them when they connect.

# Send a mail to the postmaster when a message is frozen. There are many
# reasons this could happen; one is if exim cannot deliver a mail with no
