+Exim version 4.53
+-----------------
+
+TK/01 Added the "success_on_redirect" address verification option. When an
+      address generates new addresses during routing, Exim will abort
+      verification with "success" when more than one address has been
+      generated, but continue to verify a single new address. The latter
+      does not happen when the new "success_on_redirect" option is set, like
+
+      require verify = recipient/success_on_redirect/callout=10s
+
+      In that case, verification will succeed when a router generates a new
+      address.

+      Internally, Exim includes the smoothing constant p and the options in

+      forget their past behaviour.
 
       Each ratelimit condition can have up to two options. The first option
       specifies what Exim measures the rate of, and the second specifies how
