+ 3. Authenticators now have a client_condition option. When Exim is running as
+    a client, it skips an authenticator whose client_condition expansion yields
+    "0", "no", or "false". This can be used, for example, to skip plain text
+    authenticators when the connection is not encrypted by a setting such as:
+
+      client_condition = ${if !eq{$tls_cipher}{}}
+
+    Note that the 4.67 documentation states that $tls_cipher contains the
+    cipher used for incoming messages. In fact, during SMTP delivery, it
+    contains the cipher used for the delivery. The same is true for
+    $tls_peerdn.
