+PH/04 There is a new option called acl_not_smtp_mime that allows you to scan
+ MIME parts in non-SMTP messages. It operates in exactly the same way as
+ acl_smtp_mime
+
+PH/05 It is now possible to redefine a macro within the configuration file.
+ The macro must have been previously defined within the configuration (or
+ an included file). A definition on the command line using the -D option
+ causes all definitions and redefinitions within the file to be ignored.
+ In other words, -D overrides any values that are set in the file.
+ Redefinition is specified by using '==' instead of '='. For example:
+
+ MAC1 = initial value
+ ...
+ MAC1 == updated value
+
+ Redefinition does not alter the order in which the macros are applied to
+ the subsequent lines of the configuration file. It is still the same
+ order in which the macros were originally defined. All that changes is
+ the macro's value. Redefinition makes it possible to accumulate values.
+ For example:
+
+ MAC1 = initial value
+ ...
+ MAC1 == MAC1 and something added
+
+ This can be helpful in situations where the configuration file is built
+ from a number of other files.
+
+PH/06 Macros may now be defined or redefined between router, transport,
+ authenticator, or ACL definitions, as well as in the main part of the
+ configuration. They may not, however, be changed within an individual
+ driver or ACL, or in the local_scan, retry, or rewrite sections of the
+ configuration.
+
+PH/07 $acl_verify_message is now set immediately after the failure of a
+ verification in an ACL, and so is available in subsequent modifiers. In
+ particular, the message can be preserved by coding like this:
+
+ warn !verify = sender
+ set acl_m0 = $acl_verify_message
+
+ Previously, $acl_verify_message was set only while expanding "message"
+ and "log_message" when a very denied access.
+
+PH/08 The redirect router has two new options, sieve_useraddress and
+ sieve_subaddress. These are passed to a Sieve filter to specify the :user
+ and :subaddress parts of an address. Both options are unset by default.
+ However, when a Sieve filter is run, if sieve_useraddress is unset, the
+ entire original local part (including any prefix or suffix) is used for
+ :user. An unset subaddress is treated as an empty subaddress.
+
+PH/09 Quota values can be followed by G as well as K and M.
+
+PH/10 $message_linecount is a new variable that contains the total number of
+ lines in the header and body of the message. Compare $body_linecount,
+ which is the count for the body only. During the DATA and
+ content-scanning ACLs, $message_linecount contains the number of lines
+ received. Before delivery happens (that is, before filters, routers, and
+ transports run) the count is increased to include the Received: header
+ line that Exim standardly adds, and also any other header lines that are
+ added by ACLs. The blank line that separates the message header from the
+ body is not counted. Here is an example of the use of this variable in a
+ DATA ACL:
+
+ deny message = Too many lines in message header
+ condition = \
+ ${if <{250}{${eval: $message_linecount - $body_linecount}}}
+
+ In the MAIL and RCPT ACLs, the value is zero because at that stage the
+ message has not yet been received.
+
+PH/11 In a ${run expansion, the variable $value (which contains the standard
+ output) is now also usable in the "else" string.
