New Features in Exim
--------------------
The only character affected by the ${quote_sqlite: operator is a single
quote, which it doubles.
+ The SQLite library handles multiple simultaneous accesses to the database
+ internally. Multiple readers are permitted, but only one process can
+ update at once. Attempts to access the database while it is being updated
+ are rejected after a timeout period, during which the SQLite library
+ waits for the lock to be released. In Exim, the default timeout is set
+ to 5 seconds, but it can be changed by means of the sqlite_lock_timeout
+ option.
+
Note that you must set LOOKUP_SQLITE=yes in Local/Makefile in order to
obtain SQLite support, and you will also need to add -lsqlite3 to the
EXTRALIBS setting. And of course, you have to install SQLite on your
PH/03 The use of forbid_filter_existstest now also locks out the use of the
${stat: expansion item.
+PH/04 The IGNOREQUOTA extension to the LMTP protocol is now available in both
+ the lmtp transport and the smtp transport running in LMTP mode. In the
+ lmtp transport there is a new Boolean option called ignore_quota, and in
+ the smtp transport there is a new Boolean option called
+ lmtp_ignore_quota. If either of these options is set TRUE, the string
+ "IGNOREQUOTA" is added to RCPT commands when using the LMTP protocol,
+ provided that the server has advertised support for IGNOREQUOTA in its
+ response to the LHLO command.
+
+PH/05 Previously, if "verify = helo" was set in an ACL, the condition was true
+ only if the host matched helo_try_verify_hosts, which caused the
+ verification to occur when the EHLO/HELO command was issued. The ACL just
+ 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
+
+PH/07 $smtp_command_argument is now set for all SMTP commands, not just the
+ non-message ones. This makes it possible to inspect the complete command
+ for RCPT commands, for example.
+
+PH/08 The ${eval expansion now supports % as a "remainder" operator.
