-### auth/30_exim4-config_examples
-#################################
-
-# The examples below are for server side authentication, when the
-# local exim is SMTP server and clients authenticate to the local exim.
-
-# They allow two styles of plain-text authentication against an
-# CONFDIR/passwd file whose syntax is described in exim4_passwd(5).
-
-# Hosts that are allowed to use AUTH are defined by the
-# auth_advertise_hosts option in the main configuration. The default is
-# "*", which allows authentication to all hosts over all kinds of
-# connections if there is at least one authenticator defined here.
-# Authenticators which rely on unencrypted clear text passwords don't
-# advertise on unencrypted connections by default. Thus, it might be
-# wise to set up TLS to allow encrypted connections. If TLS cannot be
-# used for some reason, you can set AUTH_SERVER_ALLOW_NOTLS_PASSWORDS to
-# advertise unencrypted clear text password based authenticators on all
-# connections. As this is severely reducing security, using TLS is
-# preferred over allowing clear text password based authenticators on
-# unencrypted connections.
-
-# PLAIN authentication has no server prompts. The client sends its
-# credentials in one lump, containing an authorization ID (which we do not
-# use), an authentication ID, and a password. The latter two appear as
-# $auth2 and $auth3 in the configuration and should be checked against a
-# valid username and password. In a real configuration you would typically
-# use $auth2 as a lookup key, and compare $auth3 against the result of the
-# lookup, perhaps using the crypteq{}{} condition.
-
-# plain_server:
-# driver = plaintext
-# public_name = PLAIN

-# server_prompts = :
-# .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
-# server_advertise_condition = ${if eq{$tls_cipher}{}{}{*}}

-
-# LOGIN authentication has traditional prompts and responses. There is no
-# authorization ID in this mechanism, so unlike PLAIN the username and
-# password are $auth1 and $auth2. Apart from that you can use the same
-# server_condition setting for both authenticators.

+#################################
+
+# These routers deal with mail meant for virtual_domains and real_domains.
+# The targets for addresses in these domains and hosts are taken from
+# the LDAP server.
+#
+# The first two routers check the LDAP directory to find an object to
+# which the mail should be delivered. The first one works on
+# virtual_domains, and finds an object based on the mail or
+# alternateMailAddress attributes. For example, info@stdin.nl might be
+# resolved by that one. The second one works on real_domains and finds an
+# object based its uid (i.e., username). For example,
+# matthijs@login.drsnuggles.stderr.nl might be resolved by the second
+# router.
+#
+# The next set of routers works when a person is retrieved. They handle
+# forwarding the mail to another mail server when the mailHost attribute
+# is set but it is not us, forwarding the email to any
+# mailForwardingAddresses in the object or delivering the mail locally
+# when the mailHost is set. Note that both either or both of the last
+# two routers can apply. If none of these three apply, routing continues
+# to the last set. Local delivery works by redirecting to username@localhost
+# and redirecting to the local_delivery router. This allows for a number of
+# different routers (put after the local_delivery router) to handle the
+# local_delivery. This is also the only way to get to any routers after the
+# ones in this file!
+#
+# The last two routers work when a group is retrieved. They handle
+# forwarding the mail to any members, both rfc822members (ie, addresses)
+# and uniqueMembers (ie, other LDAP objects).
+#
+# Note that this distinction between persons and groups is not made by
+# looking at the object classes, but at the attributes. Any object that
+# has a mailHost and/or mailForwardingAddresses is treated as a person,
+# meaning that only these two attributes are processed. Any object that
+# has neither of these attributes is assumed to be a group and has its
+# rfc822members and uniqueMembers processed. Any object that has none of
+# these properties, will cause a delivery failure.
+#
+# Note also that only the first two routers have the domains
+# precondition set, to differentiate between virtual_domains and
+# real_domains. Assuming that the routers in this file will only be called for
+# virtual_domains and real_domains, exactly one of these two routers will be
+# called. If the lookup fails, the more option ensures that the rest of the
+# routers are not called.
+#
+# The routers in this file assume that the url to LDAP server is defined
+# as LDAPSERVER and the base dn is defined as LDAPBASE. No assumptions
+# are made about the structure of the LDAP directory, so any object that
+# has the mail or mailForwardingAddress attributes is considered a
+# valid target for email, anywhere in the directory. These routers do
+# assume that a single email address is listed only once. If not, mails
+# to the address will be deferred.
