 Change log file for Exim from version 4.21

     now done for all such subprocesses. The other cases are: ${run, transport
     filters, and the commands run by the lmtp and pipe transports.
 
- 5. Added CONFIGURE_GROUP build-time option.
+ 6. Added CONFIGURE_GROUP build-time option.
+
+ 7. Some older OS have a limit of 256 on the maximum number of file
+    descriptors. Exim was using setrlimit() to set 1000 as a large value
+    unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
+    systems. I've change it so that if it can't get 1000, it tries for 256.
+
+ 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
+    was an oversight, and furthermore, ever since the addition of extra
+    controls (e.g. 4.43/32), the checks on when to allow different forms of
+    "control" were broken. There should now be diagnostics for all cases when a
+    control that does not make sense is encountered.
+
+ 9. Added the /retain_sender option to "control=submission".
+
+10. $recipients is now available in the predata ACL (oversight).
+
+11. Tidy the search cache before the fork to do a delivery from a message
+    received from the command line. Otherwise the child will trigger a lookup
+    failure and thereby defer the delivery if it tries to use (for example) a
+    cached ldap connection that the parent has called unbind on.
+
+12. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
+    of $address_data from the recipient verification was clobbered by the
+    sender verification.
+
+13. The value of address_data from a sender verification is now available in
+    $sender_address_data in subsequent conditions in the ACL statement.
+
+14. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
+
+15. Added a new option "connect=<time>" to callout options, to set a different
+    connection timeout.
+
+16. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
+    was its contents. (It was OK if the option was not defined at all.)
+
+17. A "Completed" log line is now written for messages that are removed from
+    the spool by the -Mrm option.
+
+18. New variables $sender_verify_failure and $recipient_verify_failure contain
+    information about exactly what failed.
+
+19. Added -dd to debug only the daemon process.
+
+20. Incorporated Michael Haardt's patch to ldap.c for improving the way it
+    handles timeouts, both on the server side and network timeouts. Renamed the
+    CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
+
+21. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
+    It is now set to "smtps".
+
+22. $host_address is now set to the target address during the checking of
+    ignore_target_hosts.
+
+23. When checking ignore_target_hosts for an ipliteral router, no host name was
+    being passed; this would have caused $sender_host_name to have been used if
+    matching the list had actually called for a host name (not very likely,
+    since this list is usually IP addresses). A host name is now passed as
+    "[x.x.x.x]".
+
+24. Changed the calls that set up the SIGCHLD handler in the daemon to use the
+    code that specifies a non-restarting handler (typically sigaction() in
+    modern systems) in an attempt to fix a rare and obscure crash bug.
+
+25. Narrowed the window for a race in the daemon that could cause it to ignore
+    SIGCHLD signals. This is not a major problem, because they are used only to
+    wake it up if nothing else does.
+
+26. A malformed maildirsize file could cause Exim to calculate negative values
+    for the mailbox size or file count. Odd effects could occur as a result.
+    The maildirsize information is now recalculated if the size or filecount
+    end up negative.
+
+27. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
+    support for a long time. Removed HAVE_SYS_VFS_H.
+
+28. Installed the latest version of exipick from John Jetmore.
+
+29. In an address list, if the pattern was not a regular expression, an empty
+    subject address (from a bounce message) matched only if the pattern was an
+    empty string. Non-empty patterns were not even tested. This was the wrong
+    because it is perfectly reasonable to use an empty address as part of a
+    database query. An empty address is now tested by patterns that are
+    lookups. However, all the other forms of pattern expect the subject to
+    contain a local part and a domain, and therefore, for them, an empty
+    address still always fails if the pattern is not itself empty.
+
+30. Exim went into a mad DNS loop when attempting to do a callout where the
+    host was specified on an smtp transport, and looking it up yielded more
+    than one IP address.
+
+31. Re-factored the code for checking spool and log partition space into a
+    function that finds that data and another that does the check. The former
+    is then used to implement four new variables: $spool_space, $log_space,
+    $spool_inodes, and $log_inodes.
+
+32. The RFC2047 encoding function was originally intended for short strings
+    such as real names; it was not keeping to the 75-character limit for
+    encoded words that the RFC imposes. It now respects the limit, and
+    generates multiple encoded words if necessary. To be on the safe side, I
+    have increased the buffer size for the ${rfc2047: expansion operator from
+    1024 to 2048 bytes.
+
+33. It is now permitted to omit both strings after an "if" condition; if the
+    condition is true, the result is "true". As before, when the second string
+    is omitted, a false condition yields an empty string. This makes it less
+    cumbersome to write custom ACL and router conditions.
+
+34. Failure to deliver a bounce message always caused it to be frozen, even if
+    there was an errors_to setting on the router. The errors_to setting is now
+    respected.
+
+35. If an IPv6 address is given for -bh or -bhc, it is now converted to the
+    canonical form (fully expanded) before being placed in
+    $sender_host_address.
