Oh, I am behind a netgear router. I also have a static IP from ISP.

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.

# 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 = localhost:xxxx.com:xxx.xxxx.com

# Allow mail addressed to our hostname, or to our IP address.

local_domains_include_host = true
local_domains_include_host_literals = true

# If this is uncommented, we accept and relay mail for all domains we are
# 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.

# The setting below would, if uncommented, cause Exim to check the syntax of
# all the headers that are supposed to contain email addresses (To:, From:,
# etc). This reduces the level of bounced bounces considerably.

# Exim contains support for the Realtime Blocking List (RBL), and the many
# similar services that are being maintained as part of the DNS. See
# http://www.mail-abuse.org/ for background. The line below, if uncommented,

# from hosts in a list of dynamic-IP dialups. Note that MAPS may charge
# for this service.

#rbl_domains = rbl.mail-abuse.org/reject : dialups.mail-abuse.org/warn

# http://www.rfc-ignorant.org is another interesting site with a number of
# services you can use with the rbl_domains option

# The setting below allows your host to be used as a mail relay only by
# localhost: it locks out the use of your host as a mail relay by any
# other host. See the section of the manual entitled "Control of relaying"
# for more info.

host_accept_relay = 127.0.0.1 : ::::1
# host_accept_relay = xxxxx.com : localhost

# x@y and sent on. Otherwise x%y is treated as an ordinary local part

# percent_hack_domains=*

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

# SMTP connections; otherwise it is not.

# 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
# by the pattern.

gecos_pattern = ^([^,:]*)
gecos_name = $1

# This sets the maximum number of messages that will be accepted in one
# connection and immediately delivered. If one connection sends more
# messages than this, any further ones are accepted and queued but not

# 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

# systems is if a DNS lookup of a smarthost fails. Read the documentation
# for more details: you might like to look at the auto_thaw option

# This would make exim advertise the 8BIT-MIME option. According to

# set this option you are asking exim to lie and not be RFC
# compliant. But some people want it.

# which should have user IDs in the first column and crypted passwords
# in the second.

# plain:
# driver = plaintext
# public_name = PLAIN

# These examples below are the equivalent for client side authentication.
# They assume that you only use client side authentication to connect to
# one host (such as a smarthost at your ISP), or else use the same user
# name and password everywhere

# plain:
# driver = plaintext
# public_name = PLAIN
# client_send = "^username^password"
#
# login:
# driver = plaintext
# public_name = LOGIN
# client_send = ": username : password"

I had similar issues with exim4/sarge. There were two main settings needed: 'smarthost' is the name of SMTP server (which does not require authentication in my case) and 'primary hostname' which must be a registered entry. The relevant parts of the config files look like:

Quote:
siim@tibu:/etc/exim4$ cat update-exim4.conf.conf
# /etc/exim4/update-exim4.conf.conf
#
# Edit this file and /etc/mailname by hand and execute update-exim4.conf
# yourself or use 'dpkg-reconfigure exim4-config'

dc_eximconfig_configtype='internet'
dc_other_hostnames=''
dc_local_interfaces='127.0.0.1'
dc_readhost='hugo.obs.ee'
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='mail.neti.ee'

CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='false'
This one was generated with 'dpkg-reconfigure exim4-config'; and

Quote:
siim@tibu:/etc/exim4$ head -30 exim4.conf.template
#####################################################
### main/01_exim4-config_listmacrosdefs
#####################################################

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

primary_hostname = mail.neti.ee

######################################################################
# MAIN CONFIGURATION SETTINGS #

...
Unfortunately I know nothing about exim3.

Perhaps it helps.
