-        To forward mails to an external address. For instance,
-        the value `{ "user@example.com" = "user@elsewhere.com"; }`
-        means that mails to `user@example.com` are forwarded to
-        `user@elsewhere.com`. The difference with the
-        {option}`mailserver.aliases` option is that `user@elsewhere.com`
-        can't send mail as `user@example.com`. Also, this option
-        allows to forward mails to external addresses.
+        Forwards route mail from local addresses to one or more local or external addresses.
+
+        Unlike {option}`mailserver.aliases`, the target addresses cannot send
+        mail using the forward address.
