+  # The following section of the ACL is concerned with local parts that contain

+  #
+  # Non-alphanumeric characters other than dots are rarely found in genuine
+  # local parts, but are often tried by people looking to circumvent
+  # relaying restrictions. Therefore, although they are valid in local
+  # parts, these rules disallow certain non-alphanumeric characters, as
+  # a precaution.
+  #
+  # Empty components (two dots in a row) are not valid in RFC 2822, but Exim
+  # allows them because they have been encountered. (Consider local parts
+  # constructed as "firstinitial.secondinitial.familyname" when applied to
+  # a name without a second initial.) However, a local part starting
+  # with a dot or containing /../ can cause trouble if it is used as part of a
+  # file name (e.g. for a mailing list). This is also true for local parts that
+  # contain slashes. A pipe symbol can also be troublesome if the local part is
+  # incorporated unthinkingly into a shell command line.
+  #
+  # These ACL components will block recipient addresses that are valid
+  # from an RFC5322 point of view. We chose to have them blocked by
+  # default for security reasons.
+  #
+  # If you feel that your site should have less strict recipient
+  # checking, please feel free to change the default values of the macros
+  # defined in main/01_exim4-config_listmacrosdefs or override them from a
+  # local configuration file.
+  #

+  # default, and is applied to messages that are addressed to one of the

+#################################
+
+# 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 $auth3 against the result of the
+# lookup, perhaps using the crypteq{}{} condition.
+
+# plain_server:
+#   driver = plaintext
+#   public_name = PLAIN
+#   server_condition = "${if crypteq{$auth3}{${extract{1}{:}{${lookup{$auth2}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"

+#   server_prompts = :
+#   .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
+#   server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}}
+#   .endif
+
+# 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.
