+Version 4.44
+------------
+
+ 1. There is a new build-time option called CONFIGURE_GROUP which works like
+ CONFIGURE_OWNER. It specifies one additional group that is permitted for
+ the runtime configuration file when the group write permission is set.
+
+ 2. The "control=submission" facility has a new option /retain_sender. This
+ has the effect of setting local_sender_retain true and local_from_check
+ false for the incoming message in which it is encountered.
+
+ 3. $recipients is now available in the predata ACL (oversight).
+
+ 4. The value of address_data from a sender verification is now available in
+ $sender_address_data in subsequent conditions in the ACL statement. Note:
+ this is just like $address_data. The value does not persist after the end
+ of the current ACL statement. If you want to preserve it, you can use one
+ of the ACL variables.
+
+ 5. The redirect router has two new options: forbid_sieve_filter and
+ forbid_exim_filter. When filtering is enabled by allow_filter, these
+ options control which type(s) of filtering are permitted. By default, both
+ Exim and Sieve filters are allowed.
+
+ 6. A new option for callouts makes it possible to set a different (usually
+ smaller) timeout for making the SMTP connection. The keyword is "connect".
+ For example:
+
+ verify = sender/callout=5s,connect=1s
+
+ If not specified, it defaults to the general timeout value.
+
+ 7. The new variables $sender_verify_failure and $recipient_verify_failure
+ contain information about exactly what failed. In an ACL, after one of
+ these failures, the relevant variable contains one of the following words:
+
+ qualify the address was unqualified (no domain), and the message
+ was neither local nor came from an exempted host;
+
+ route routing failed;
+
+ mail routing succeeded, and a callout was attempted; rejection
+ occurred at or before the MAIL command (that is, on initial
+ connection, HELO, or MAIL);
+
+ recipient the RCPT command in a callout was rejected;
+
+ postmaster the postmaster check in a callout was rejected.
+
+ The main use of these variables is expected to be to distinguish between
+ rejections of MAIL and rejections of RCPT.
+
+ 8. The command line option -dd behaves exactly like -d except when used on a
+ command that starts a daemon process. In that case, debugging is turned off
+ for the subprocesses that the daemon creates. Thus, it is useful for
+ monitoring the behaviour of the daemon without creating as much output as
+ full debugging.
+
+ 9. $host_address is now set to the target address during the checking of
+ ignore_target_hosts.
