 New Features in Exim

+PH/01 Support for SQLite database lookups has been added. This is another
+      query-style lookup, but it is slightly different from the others because
+      a file name is required in addition to the SQL query. This is because an
+      SQLite database is a single file and there is no daemon as in other SQL
+      databases. The interface to Exim requires the name of the file, as an
+      absolute path, to be given at the start of the query. It is separated
+      from the query by white space. This means that the path name cannot
+      contain white space. Here is a lookup expansion example:
+
+        ${lookup sqlite {/some/thing/sqlitedb \
+          select name from aliases where id='ph10';}}
+
+      In a list, the syntax is similar. For example:
+
+        domainlist relay_domains = sqlite;/some/thing/sqlitedb \
+           select * from relays where ip='$sender_host_address';
+
+      The only character affected by the ${quote_sqlite: operator is a single
+      quote, which it doubles.
+
+      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
+      host first.
+
+PH/02 The variable $message_id is now deprecated, to be replaced by
+      $message_exim_id, which makes it clearer which ID is being referenced.
+
+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.

       Each ratelimit condition can have up to two options. The first option
