-# IPv6 is coming. Exim has experimental support that has been tried out on
-# one or two OS. See the file README.IPV6 for the current status of this
-# support. Do not set this option unless you are working on IPv6 and know
-# what you are doing. As well as the basic enabling option, there are
-# parameters for include and library directories that may be needed for IPv6
-# on some systems.
+# IPv6 is gradually spreading more and more widely. Most operating systems seem
+# to support it nowadays. If you set this option, IPv6 support will be included
+# in the Exim binary. As well as the basic enabling option, there are
+# parameters for include and library directories that may be needed for IPv6 on
+# some systems, where the support is not yet in the standard library.
