I have shot myself in the foot. I did something to my config
file that results in many messages that come in from a mailing
list be marked as recipient unknown.
What I have done (or tried to do...{rueful grimace}) is set it up
so that mail for non-existent users goes to postmaster. Once a
week or so, I go through this, adding some names to the blackhole
list. (As a school we have a high turnover. I forward for a year
after they leave, then junk anything else.) At the same time I
forward obvious user mis-spellings to the correct destination.
Somewhere I am doing something that on the basis of the To:
header is rewriting the envelope-to:.
As you can see from the example, my exim mail is going to the
postmaster. (So if you reply, be sure that sbotsford@???
gets a copy so I don't have to wade through a gigabyte of spam to
find it next tuesday.)

set, the

this does
# the right thing and you need not set anything explicitly.
primary_hostname = postie.sjsa.ab.ca
# 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:

hostlist relay_from_hosts = 127.0.0.1 : 192.168.1.0/24
# 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.
message_size_limit = 10M
# 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
#acl_smtp_mime = acl_check_mime
acl_smtp_data = acl_check_content
# You should not change that setting until you understand how
ACLs work.
# 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 = sjsa.ab.ca
# 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 = sjsa.ab.ca
# 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 = 192.168.1.0/24
recipient_unqualified_hosts = 192.168.1.0/24
#
# 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.
