New Features in Exim

@@ -76,6 +76,32 @@ PH/05 Previously, if "verify = helo" was set in an ACL, the condition was true
tested the remembered result. Now, if a previous verification attempt has
not happened, "verify = helo" does it there and then.
+PH/06 It is now possible to specify a port number along with a host name or
+ IP address in the list of hosts defined in the manualroute or
+ queryprogram routers, fallback_hosts, or the "hosts" option of the smtp
+ transport. These all override any port specification on the transport.
+ The relatively standard syntax of using a colon separator has been
+ adopted, but there are some gotchas that need attention:
+
+ * In all these lists of hosts, colon is the default separator, so either
+ the colon that specifies a port must be doubled, or the separator must
+ be changed. The following two examples have the same effect:
+
+ fallback_hosts = host1.tld::1225 : host2.tld::1226
+ fallback_hosts = <; host1.tld:1225 ; host2.tld:1226
+
+ * When IPv6 addresses are involved, it gets worse, because they contain
+ colons of their own. To make this case easier, it is permitted to
+ enclose an IP address (either v4 or v6) in square brackets if a port
+ number follows. Here's an example from a manualroute router:
+
+ route_list = * "</ [10.1.1.1]:1225 / [::1]:1226"
+
+ If the "/MX" feature is to be used as well as a port specifier, the port
+ must come last. For example:
+
+ route_list = * dom1.tld/mx::1225
