Ok. I recently had to reinstall my system after the root partition died
(don't ask me how, I don't know!). I got exim setup again, and it looked
good at first, till I tried to verify my TMDA extended addresses.
[root@shortcircuit root]# exim -oMr scanned-ok -bv
dan-dated-1058367649.ba737f@???
dan-dated-1058367649.ba737f@??? failed to verify:
Unrouteable address
but dan@??? works fine. Am I missing something? I
have included my exim.conf below, I'm running Exim 4.20 on RedHat 8.
Thanks!

# Runtime configuration file for Exim #
######################################################################
# 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. There are many more than are mentioned here. The
# manual is in the file doc/spec.txt in the Exim distribution as a plain
# ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are available
# from the Exim ftp sites. The manual is also online at the Exim web sites.
# This file is divided into several parts, all but the first of which are
# headed by a line starting with the word "begin". Only those parts that
# are required need to be present. Blank lines, and lines starting with #
# are ignored.
########### IMPORTANT ########## IMPORTANT ########### IMPORTANT ###########
# #
# Whenever you change Exim's configuration file, you *must* remember to #
# HUP the Exim daemon, because it will not pick up the new configuration #
# until you do. However, any other Exim processes that are started, for #
# example, a process started by an MUA in order to send a message, will #
# see the new configuration as soon as it is in place. #
# #
# You do not need to HUP the daemon for changes in auxiliary files that #
# are referenced from this file. They are read every time they are used. #
# #
# It is usually a good idea to test a new configuration for syntactic #
# correctness before installing it (for example, by running the command #
# "exim -C /config/file.new -bV"). #

# 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. In many cases this does
# the right thing and you need not set anything explicitly.
primary_hostname = shortcircuit.dyndns.org
trusted_users = root:dan:amavis
# The next three settings create two lists of domains and one list of hosts.
# These lists are referred to later in this configuration using the syntax
# +local_domains, +relay_to_domains, and +relay_from_hosts,
respectively. They
# are all colon-separated lists:
domainlist local_domains = @:shortcircuit.dyndns.org
domainlist relay_to_domains = thedungeon.dnsalias.org
hostlist relay_from_hosts = 127.0.0.1:192.168.0.0/24
# Most straightforward access control requirements can be obtained by
# appropriate settings of the above options. In more complicated
situations, you
# may need to modify the Access Control List (ACL) which appears later
in this
# file.
# The first setting specifies your local domains, for example:
#
# domainlist local_domains = my.first.domain : my.second.domain
#
# You can use "@" to mean "the name of the local host", as in the default
# setting above. This is the name that is specified by primary_hostname,
# as specified above (or defaulted). If you do not want to do any local
# deliveries, remove the "@" from the setting above. If you want to
accept mail
# addressed to your host's literal IP address, for example, mail
addressed to
# "user@???", you can add "@[]" as an item in the local domains
# list. You also need to uncomment "allow_domain_literals" below. This
is not
# recommended for today's Internet.
# The second setting specifies domains for which your host is an
incoming relay.
# If you are not doing any relaying, you should leave the list empty.
However,
# if your host is an MX backup or gateway of some kind for some domains, you
# must set relay_to_domains to match those domains. For example:
#
# domainlist relay_to_domains = *.myco.com : my.friend.org
#
# 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 third setting specifies hosts that can use your host as an
outgoing relay
# to any other host on the Internet. Such a setting commonly refers to a
# complete local network as well as the localhost. For example:
#
# hostlist relay_from_hosts = 127.0.0.1 : 192.168.0.0/16
#
# The "/16" is a bit mask (CIDR notation), not a number of hosts. Note
that you
# have to include 127.0.0.1 if you want to allow processes on your host
to send
# SMTP mail by using the loopback address. A number of MUAs use this
method of
# sending mail.
# All three of these lists may contain many different kinds of item,
including
# wildcarded names, regular expressions, and file lookups. See the reference
# manual for details. The lists above are used in the access control
list for
# incoming messages. The name of this ACL is defined here:
acl_smtp_rcpt = acl_check_rcpt
# You should not change that setting until you understand how ACLs work.
hide mysql_servers = <hidden>
# 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 recipient_unqualified_hosts option 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 =
# The following line must be uncommented if you want Exim to recognize
# addresses of the form "user@???" that is, with a "domain
literal"
# (an IP address) instead of a named domain. The RFCs still require this
form,
# but it makes little sense to permit mail to be sent to specific hosts by
# their IP address in the modern Internet. This ancient format has been used
# by those seeking to abuse hosts by using them for unwanted relaying.
If you
# really do want to support domain literals, uncomment the following
line, and
# see also the "domain_literal" router below.
# allow_domain_literals
# No deliveries will ever be run under the uids of these users (a colon-
# separated list). An attempt to do so causes a panic error to be
logged, and
# the delivery to be deferred. This is a paranoic safety catch. Note
that 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.
host_lookup = *
# The settings below, which are actually the same as the defaults in the
# code, cause Exim to make RFC 1413 (ident) callbacks for all incoming SMTP
# calls. You can limit the hosts to which these calls are made, and/or
change
# the timeout that is used. If you set the timeout to zero, all RFC 1413
calls
# are disabled. RFC 1413 calls are cheap and can provide useful information
# for tracing problem messages, but some hosts and firewalls have problems
# with them. This can result in a timeout instead of an immediate refused
# connection, leading to delays on starting up an SMTP session.
rfc1413_hosts = *
rfc1413_query_timeout = 30s
# 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
#
# sender_unqualified_hosts =
# recipient_unqualified_hosts =
#
# to control sender and recipient addresses, respectively. When this is
done,
# unqualified addresses are qualified using the settings of qualify_domain
# and/or qualify_recipient (see above).
# If you want Exim to support the "percent hack" for certain domains,
# uncomment the following line and provide a list of domains. The "percent
# hack" is the feature by which mail addressed to x%y@z (where z is one of
# the domains listed) is locally rerouted to x@y and sent on. If z is
not one
# of the "percent hack" domains, x%y is treated as an ordinary local
part. This
# hack is rarely needed nowadays; you should not enable it unless you
are sure
# that you really need it.
#
# percent_hack_domains =
#
# As well as setting this option you will also need to remove the test
# for local parts containing % in the ACL definition below.
# When Exim can neither deliver a message nor return it to sender, it
"freezes"
# the delivery error message (aka "bounce message"). There are also other
# circumstances in which messages get frozen. They will stay on the
queue for
# ever unless one of the following options is set.
# This option unfreezes frozen bounce messages after two days, tries
# once more to deliver them, and ignores any delivery failures.

automatically,
# the name gets inserted into this file from whatever is set in Exim's
# build-time configuration. The default path is the traditional
/etc/aliases.
# If you install this configuration by hand, you need to specify the correct

default.
