+# configurations for plaintext username/password authentication. This kind

# AUTHENTICATION CONFIGURATION #
######################################################################
-# There are no authenticator specifications in this default configuration file.
+# The following authenticators support plaintext username/password
+# authentication using the standard PLAIN mechanism and the traditional
+# but non-standard LOGIN mechanism, with Exim acting as the server.
+# PLAIN and LOGIN are enough to support most MUA software.
+#
+# These authenticators are not complete: you need to change the
+# server_condition settings to specify how passwords are verified.
+# They are set up to offer authentication to the client only if the
+# connection is encrypted with TLS, so you also need to add support
+# for TLS. See the global configuration options section at the start
+# of this file for more about TLS.
+#
+# The default RCPT ACL checks for successful authentication, and will accept
+# messages from authenticated users from anywhere on the Internet.
begin authenticators
+# 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:
+# driver = plaintext
+# server_set_id = $auth2
+# server_prompts = :
+# server_condition = Authentication is not yet configured
+# server_advertise_condition = ${if def: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.
+
+#LOGIN:
+# driver = plaintext
+# server_set_id = $auth1
+# server_prompts = <| Username: | Password:
+# server_condition = Authentication is not yet configured
+# server_advertise_condition = ${if def:tls_cipher }
