 Change log file for Exim from version 4.21
 -------------------------------------------
 
+Exim version 4.64
+-----------------
+
+TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
+      leftover -K file (the existence of which was triggered by #402).
+      While we were at it, introduced process PID as part of the -K
+      filename. This should rule out race conditions when creating
+      these files.
+
+TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
+      processing considerably. Previous code took too long for large mails,
+      triggering a timeout which in turn triggers #401.
+
+TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
+      in the DK code in transports.c. sendfile() is not really portable,
+      hence the _LINUX specificness.
+
+TF/01 In the add_headers option to the mail command in an Exim filter,
+      there was a bug that Exim would claim a syntax error in any
+      header after the first one which had an odd number of characters
+      in the field name.
+
+PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
+      callout verification, Exim cached a "reject" for the entire domain. This
+      is correct for most verifications, but it is not correct for a recipient
+      verification with use_sender or use_postmaster set, because in that case
+      the callout does not use MAIL FROM:<>. Exim now distinguishes the special
+      case of MAIL FROM:<> rejection from other early rejections (e.g.
+      rejection of HELO). When verifying a recipient using a non-null MAIL
+      address, the cache is ignored if it shows MAIL FROM:<> rejection.
+      Whatever the result of the callout, the value of the domain cache is
+      left unchanged (for any other kind of callout, getting as far as trying
+      RCPT means that the domain itself is ok).
+
+PH/02 Tidied a number of unused variable and signed/unsigned warnings that
+      gcc 4.1.1 threw up.
+
+PH/03 On Solaris, an unexpectedly close socket (dropped connection) can
+      manifest itself as EPIPE rather than ECONNECT. When tidying away a
+      session, the daemon ignores ECONNECT errors and logs others; it now
+      ignores EPIPE as well.
+
+PH/04 Applied Nico Erfurth's refactoring patch to tidy up mime.c
+      (quoted-printable decoding).
+
+PH/05 Applied Nico Erfurth's refactoring patch to tidy up spool_mbox.c, and
+      later the small subsequent patch to fix an introduced bug.
+
+PH/06 Installed the latest Cygwin Makefile from the Cygwin maintainer.
+
+PH/07 There was no check for overflow in expansions such as ${if >{1}{4096M}}.
+
+PH/08 An error is now given if message_size_limit is specified negative.
+
+PH/09 Applied and tidied up Jakob Hirsch's patch for allowing ACL variables
+      to be given (somewhat) arbitrary names.
+
+JJ/01 exipick 20060919.0, allow for arbitrary acl_ variables introduced
+      in 4.64-PH/09.
+
+JJ/02 exipick 20060919.0, --show-vars args can now be regular expressions,
+      miscellaneous code fixes
+
+PH/10 Added the log_reject_target ACL modifier to specify where to log
+      rejections.
+
+PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
+      hostname. This is wrong, because it relates to the incoming message (and
+      probably the interface on which it is arriving) and not to the outgoing
+      callout (which could be using a different interface). This has been
+      changed to use the value of the helo_data option from the smtp transport
+      instead - this is what is used when a message is actually being sent. If
+      there is no remote transport (possible with a router that sets up host
+      addresses), $smtp_active_hostname is used.
+
+PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
+      tweaks were necessary in order to get it to work (see also 21 below):
+      (a) The code assumed that strncpy() returns a negative number on buffer
+          overflow, which isn't the case. Replaced with Exim's string_format()
+          function.
+      (b) There were several signed/unsigned issues. I just did the minimum
+          hacking in of casts. There is scope for a larger refactoring.
+      (c) The code used strcasecmp() which is not a standard C function.
+          Replaced with Exim's strcmpic() function.
+      (d) The code set only $1; it now sets $auth1 as well.
+      (e) A simple test gave the error "authentication client didn't specify
+          service in request". It would seem that Dovecot has changed its
+          interface. Fortunately there's a specification; I followed it and
+          changed what the client sends and it appears to be working now.
+
+PH/13 Added $message_headers_raw to provide the headers without RFC 2047
+      decoding.
+
+PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
+      address A is aliased to B and C, where B exists and C does not. Without
+      -v the output is "A verified" because verification stops after a
+      successful redirection if more than one address is generated. However,
+      with -v the child addresses are also verified. Exim was outputting "A
+      failed to verify" and then showing the successful verification for C,
+      with its parentage. It now outputs "B failed to verify", showing B's
+      parentage before showing the successful verification of C.
+
+PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
+      look up a TXT record in a specific list after matching in a combined
+      list.
+
+PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
+      RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
+      they consult the DNS. I had assumed they would set it the way they
+      wanted; and indeed my experiments on Linux seem to show that in some
+      cases they do (I could influence IPv6 lookups but not IPv4 lookups).
+      To be on the safe side, however, I have now made the interface to
+      host_find_byname() similar to host_find_bydns(), with an argument
+      containing the DNS resolver options. The host_find_byname() function now
+      sets these options at its start, just as host_find_bydns() does. The smtp
+      transport options dns_qualify_single and dns_search_parents are passed to
+      host_find_byname() when gethostbyname=TRUE in this transport. Other uses
+      of host_find_byname() use the default settings of RES_DEFNAMES
+      (qualify_single) but not RES_DNSRCH (search_parents).
+
+PH/17 Applied (a modified version of) Nico Erfurth's patch to make
+      spool_read_header() do less string testing, by means of a preliminary
+      switch on the second character of optional "-foo" lines. (This is
+      overdue, caused by the large number of possibilities that now exist.
+      Originally there were few.) While I was there, I also converted the
+      str(n)cmp tests so they don't re-test the leading "-" and the first
+      character, in the hope this might squeeze out yet more improvement.
+
+PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
+      flag allowing group syntax was set by the header_syntax check but not
+      turned off, possible causing trouble later; (2) The flag was not being
+      set at all for the header_verify test, causing "group"-style headers to
+      be rejected. I have now set it in this case, and also caused header_
+      verify to ignore an empty address taken from a group. While doing this, I
+      came across some other cases where the code for allowing group syntax
+      while scanning a header line wasn't quite right (mostly, not resetting
+      the flag correctly in the right place). These bugs could have caused
+      trouble for malformed header lines. I hope it is now all correct.
+
+PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
+      with the "reply" argument non-NULL. The code, however (which originally
+      came from elsewhere) had *some* tests for NULL when it wrote to *reply,
+      but it didn't always do it. This confused somebody who was copying the
+      code for some other use. I have removed all the tests.
+
+PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
+      feature that was used to support insecure browsers during the U.S. crypto
+      embargo. It requires special client support, and Exim is probably the
+      only MTA that supported it -- and would never use it because real RSA is
+      always available. This code has been removed, because it had the bad
+      effect of slowing Exim down by computing (never used) parameters for the
+      RSA_EXPORT functionality.
+
+PH/21 On the advice of Timo Sirainen, added a check to the dovecot
+      authenticator to fail if there's a tab character in the incoming data
+      (there should never be unless someone is messing about, as it's supposed
+      to be base64-encoded). Also added, on Timo's advice, the "secured" option
+      if the connection is using TLS or if the remote IP is the same as the
+      local IP, and the "valid-client-cert option" if a client certificate has
+      been verified.
+
+PH/22 As suggested by Dennis Davis, added a server_condition option to *all*
+      authenticators. This can be used for authorization after authentication
+      succeeds. (In the case of plaintext, it servers for both authentication
+      and authorization.)
+
+PH/23 Testing for tls_required and lost_connection in a retry rule didn't work
+      if any retry times were supplied.
+
+PH/24 Exim crashed if verify=helo was activated during an incoming -bs
+      connection, where there is no client IP address to check. In this
+      situation, the verify now always succeeds.
+
+PH/25 Applied John Jetmore's -Mset patch.
+
+PH/26 Added -bem to be like -Mset, but loading a message from a file.
+
+PH/27 In a string expansion for a processed (not raw) header when multiple
+      headers of the same name were present, leading whitespace was being
+      removed from all of them, but trailing whitespace was being removed only
+      from the last one. Now trailing whitespace is removed from each header
+      before concatenation. Completely empty headers in a concatenation (as
+      before) are ignored.
+
+PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John
+      Jetmore). It would have mis-read ACL variables from pre-4.61 spool files.
+
+PH/29 [Removed. This was a change that I later backed out, and forgot to
+      correct the ChangeLog entry (that I had efficiently created) before
+      committing the later change.]
+
+PH/30 Exim was sometimes attempting to deliver messages that had suffered
+      address errors (4xx response to RCPT) over the same connection as other
+      messages routed to the same hosts. Such deliveries are always "forced",
+      so retry times are not inspected. This resulted in far too many retries
+      for the affected addresses. The effect occurred only when there were more
+      hosts than the hosts_max_try setting in the smtp transport when it had
+      the 4xx errors. Those hosts that it had tried were not added to the list
+      of hosts for which the message was waiting, so if all were tried, there
+      was no problem. Two fixes have been applied:
+
+      (i)  If there are any address or message errors in an SMTP delivery, none
+           of the hosts (tried or untried) are now added to the list of hosts
+           for which the message is waiting, so the message should not be a
+           candidate for sending over the same connection that was used for a
+           successful delivery of some other message. This seems entirely
+           reasonable: after all the message is NOT "waiting for some host".
+           This is so "obvious" that I'm not sure why it wasn't done
+           previously. Hope I haven't missed anything, but it can't do any
+           harm, as the worst effect is to miss an optimization.
+
+      (ii) If, despite (i), such a delivery is accidentally attempted, the
+           routing retry time is respected, so at least it doesn't keep
+           hammering the server.
+
+PH/31 Installed Andrew Findlay's patch to close the writing end of the socket
+      in ${readsocket because some servers need this prod.
+
+PH/32 Added some extra debug output when updating a wait-xxx database.
+
+PH/33 The hint "could be header name not terminated by colon", which has been
+      given for certain expansion errors for a long time, was not being given
+      for the ${if def:h_colon_omitted{...  case.
+
+PH/34 The spec says: "With one important exception, whenever a domain list is
+      being scanned, $domain contains the subject domain." There was at least
+      one case where this was not true.
+
+PH/35 The error "getsockname() failed: connection reset by peer" was being
+      written to the panic log as well as the main log, but it isn't really
+      panic-worthy as it just means the connection died rather early on. I have
+      removed the panic log writing for the ECONNRESET error when getsockname()
+      fails.
+
+PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
+      runs only) independently of the message's sender address. This meant
+      that, if the 4xx error was in fact related to the sender, a different
+      message to the same recipient with a different sender could confuse
+      things. In particualar, this can happen when sending to a greylisting
+      server, but other circumstances could also provoke similar problems.
+      I have changed the default so that the retry time for these errors is now
+      based a combination of the sender and recipient addresses. This change
+      can be overridden by setting address_retry_include_sender=false in the
+      smtp transport.
+
+PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the
+      remote server are returned as part of bounce messages. This was not
+      happening for LMTP over a pipe (the lmtp transport), but now it is the
+      same for both kinds of LMTP.
+
+PH/38 Despite being documented as not happening, Exim was rewriting addresses
+      in header lines that were in fact CNAMEs. This is no longer the case.
+
+PH/39 If -R or -S was given with -q<time>, the effect of -R or -S was ignored,
+      and queue runs started by the daemon processed all messages. This has
+      been fixed so that -R and -S can now usefully be given with -q<time>.
+
+PH/40 Import PCRE release 6.7 (fixes some bugs).
+
+PH/41 Add bitwise logical operations to eval (courtesy Brad Jorsch).
+
+PH/42 Give an error if -q is specified more than once.
+
+PH/43 Renamed the variables $interface_address and $interface_port as
+      $received_ip_address and $received_port, to make it clear that these
+      values apply to message reception, and not to the outgoing interface when
+      a message is delivered. (The old names remain recognized, of course.)
+
+PH/44 There was no timeout on the connect() call when using a Unix domain
+      socket in the ${readsocket expansion. There now is.
+
+PH/45 Applied a modified version of Brad Jorsch's patch to allow "message" to
+      be meaningful with "accept".
+
+SC/01 Eximstats V1.43
+     Bug fix for V1.42 with -h0 specified. Spotted by Chris Lear.
+
+SC/02 Eximstats V1.44
+      Use a glob alias rather than an array ref in the generated
+      parser. This improves both readability and performance.
+
+SC/03 Eximstats V1.45 (Marco Gaiarin / Steve Campbell)
+      Collect SpamAssassin and rejection statistics.
+      Don't display local sender or destination tables unless
+      there is data to show.
+      Added average volumes into the top table text output.
+
+SC/04 Eximstats V1.46
+      Collect data on the number of addresses (recipients)
+      as well as the number of messages.
+
+SC/05 Eximstats V1.47
+      Added 'Message too big' to the list of mail rejection
+      reasons (thanks to Marco Gaiarin).
+
+SC/06 Eximstats V1.48
+      Mainlog lines which have GMT offsets and are too short to
+      have a flag are now skipped.
+
+SC/07 Eximstats V1.49 (Alain Williams)
+      Added the -emptyok flag.
+
+SC/08 Eximstats V1.50
+      Fixes for obtaining the IP address from reject messages.
+
+JJ/03 exipick.20061117.2, made header handling as similar to exim as possible
+      (added [br]h_ prefixes, implemented RFC2047 decoding.  Fixed
+      whitesspace changes from 4.64-PH/27
+
+JJ/04 exipick.20061117.2, fixed format and added $message_headers_raw to
+      match 4.64-PH/13
+
+JJ/05 exipick.20061117.2, bug fixes (error out sooner when invalid criteria
+      are found, allow negative numbers in numeric criteria)
+
+JJ/06 exipick.20061117.2, added new $message_body_missing variable
+
+JJ/07 exipick.20061117.2, added $received_ip_address and $received_port
+      to match changes made in 4.64-PH/43
+
+
+
+Exim version 4.63
+-----------------
+
+SC/01 Use a glob alias rather than an array ref in eximstats generated
+      parser. This improves both readability and performance.
+
+SC/02 Collect SpamAssassin and rejection statistics in eximstats.
+      Don't display local sender or destination tables in eximstats unless
+      there is data to show.
+      Added average volumes into the eximstats top table text output.
+
+SC/03 Collect data on the number of addresses (recipients) as well
+      as the number of messages in eximstats.
+
+TF/01 Correct an error in the documentation for the redirect router. Exim
+      does (usually) call initgroups() when daemonizing.
+
+TF/02 Call initgroups() when dropping privilege in exim.c, so that Exim runs
+      with consistent privilege compared to when running as a daemon.
+
+TF/03 Note in the spec that $authenticated_id is not set for local
+      submissions from trusted users.
+
+TF/04 The ratelimit per_rcpt option now works correctly in acl_not_smtp.
+      Thanks to Dean Brooks <dean@iglou.com> for the patch.
+
+TF/05 Make it easier to get SMTP authentication and TLS/SSL support working
+      by adding some example configuration directives to the default
+      configuration file. A little bit of work is required to uncomment the
+      directives and define how usernames and passwords are checked, but
+      there is now a framework to start from.
+
+PH/01 Added #define LDAP_DEPRECATED 1 to ldap.c because some of the "old"
+      functions that Exim currently uses aren't defined in ldap.h for OpenLDAP
+      without this. I don't know how relevant this is to other LDAP libraries.
+
+PH/02 Add the verb name to the "unknown ACL verb" error.
+
+PH/03 Magnus Holmgren's patch for filter_prepend_home.
+
+PH/03 Fixed Bugzilla #101: macro definition between ACLs doesn't work.
+
+PH/04 Applied Magnus Holmgren's patch to fix Bugzilla #98: transport's home
+      directory not expanded when it should be if an expanded home directory
+      was set for the address (which is overridden by the transport).
+
+PH/05 Applied Alex Kiernan's patch to fix Bugzilla #99: a problem with
+      libradius.
+
+PH/06 Added acl_not_smtp_start, based on Johannes Berg's patch, and set the
+      bit to forbid control=suppress_local_fixups in the acl_not_smtp ACL,
+      because it is too late at that time, and has no effect.
+
+PH/07 Changed ${quote_pgsql to quote ' as '' instead of \' because of a
+      security issue with \' (bugzilla #107). I could not use the
+      PQescapeStringConn() function, because it needs a PGconn value as one of
+      its arguments.
+
+PH/08 When testing addresses using -bt, indicate those final addresses that
+      are duplicates that would not cause an additional delivery. At least one
+      person was confused, thinking that -bt output corresponded to deliveries.
+      (Suppressing duplicates isn't a good idea as you lose the information
+      about possibly different redirections that led to the duplicates.)
+
+PH/09 Applied patch from Erik to use select() instead of poll() in spam.c on
+      systems where poll() doesn't work, in particular OS X.
+
+PH/10 Added more information to debugging output for retry time not reached.
+
+PH/11 Applied patch from Arkadiusz Miskiewicz to apply a timeout to read
+      operations in malware.c.
+
+PH/12 Applied patch from Magnus Holmgren to include the "h" tag in Domain Keys
+      signatures.
+
+PH/13 If write_rejectlog was set false when logging was sent to syslog with
+      syslog_duplication set false, log lines that would normally be written
+      both the the main log and to the reject log were not written to syslog at
+      all.
+
+PH/14 In the default configuration, change the use of "message" in ACL warn
+      statements to "add_header".
+
+PH/15 Diagnose a filter syntax error for "seen", "unseen", or "noerror" if not
+      not followed by a command (e.g. "seen endif").
+
+PH/16 Recognize SMTP codes at the start of "message" in ACLs and after :fail:
+      and :defer: in a redirect router. Add forbid_smtp_code to suppress the
+      latter.
+
+PH/17 Added extra conditions to the default value of delay_warning_condition
+      so that it is now:
+
+        ${if or { \
+            { !eq{$h_list-id:$h_list-post:$h_list-subscribe:}{} } \
+            { match{$h_precedence:}{(?i)bulk|list|junk} } \
+            { match{$h_auto-submitted:}{(?i)auto-generated|auto-replied} } \
+            }{no}{yes}}
+
+      The Auto-Submitted: and various List- headers are standardised, whereas I
+      don't think Precedence: ever was.
+
+PH/18 Refactored debugging code in route_finduser() to show more information,
+      in particular, the error code if getpwnam() issues one.
+
+PH/19 Added PQsetClientEncoding(conn, "SQL_ASCII") to the pgsql code module.
+      This is apparently needed in addition to the PH/07 change above to avoid
+      any possible encoding problems.
+
+PH/20 Perl can change the locale. Exim was resetting it after a ${perl call,
+      but not after initializing Perl.
+
+PH/21 Added a call to PQsetNoticeProcessor() to catch pgsql "notices" and
+      output them only if debugging. By default they are written stderr,
+      apparently, which is not desirable.
+
+PH/22 Added Alain Williams' LDAP patch to support setting REFERRALS=off on
+      queries.
+
+JJ/01 exipick: added --reverse (and -R synonym), --random, --size, --sort and
+      --not options
+
+JJ/02 exipick: rewrote --help documentation to hopefully make more clear.
+
+PH/23 Made -oMaa and -oMt work with -bh and -bs to pretend the connection is
+      authenticated or an ident call has been made. Suppress the default
+      values for $authenticated_id and $authenticated_sender (but permit -oMai
+      and -oMas) when testing with -bh.
+
+PH/24 Re-jigged the order of the tests in the default configuration so that the
+      tests for valid domains and recipients precede the DNS black list and CSA
+      tests, on the grounds that those ones are more expensive.

+PH/25 Exim was not testing for a space following SMTP commands such as EHLO
+      that require one. Thus, EHLORHUBARB was interpreted as a valid command.

+PH/26 (n)wildlsearch lookups are documented as being done case-insensitively.
+      However, an attempt to turn on case-sensitivity in a regex key by
+      including (?-i) didn't work because the subject string was already
+      lowercased, and the effects were non-intuitive. It turns out that a

+Exim version 4.62
+-----------------
+
+TF/01 Fix the add_header change below (4.61 PH/55) which had a bug that (amongst
+      other effects) broke the use of negated acl sub-conditions.
+
+PH/01 ${readsocket now supports Internet domain sockets (modified John Jetmore
+      patch).
+
+PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
+      "Deny" causes Exim to reject the incoming connection with a 554 error.
+      Unfortunately, if there is a major crisis, such as a disk failure,
+      tcp-wrappers gives "deny", whereas what one would like would be some
+      kind of temporary error. A kludge has been added to help with this.
+      Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
+      554 error is used if errno is still zero or contains ENOENT (which occurs
+      if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
+      451 error is used.
+
+PH/03 Add -lutil to the default FreeBSD LIBS setting.
+
+PH/04 Change PH/19 for 4.61 was too wide. It should not be applied to host
+      errors. Otherwise a message that provokes a temporary error (when other
+      messages do not) can cause a whole host to time out.
+
+PH/05 Batch deliveries by appendfile and pipe transports did not work when the
+      addresses were routed directly to files or pipes from a redirect router.
+      File deliveries just didn't batch; pipe deliveries might have suffered
+      odd errors.
+
+PH/06 A failure to get a lock for a hints database would erroneously always say
+      "Failed to get write lock", even when it was really a read lock.
+
+PH/07 The appendfile transport was creating MBX lock files with a fixed mode
+      of 0600. This has been changed to use the value of the lockfile_mode
+      option (which defaults to 0600).
+
+PH/08 Applied small patch from the Sieve maintainer.
+
+PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
+      folder from quota calculations, a direct delivery into this folder messed
+      up the contents of the maildirsize file. This was because the regex was
+      used only to exclude .Trash (or whatever) when the size of the mailbox
+      was calculated. There was no check that a delivery was happening into an
+      excluded directory. This bug has been fixed by ignoring all quota
+      processing for deliveries into excluded directories.
+
+PH/10 Added the maildirfolder_create_regex option to appendfile.

+      if the "connect()" function timed out, ip_connect() used to close the
+      socket. However, verify_get_ident() also closes the socket later, and in
+      between Exim writes to the log, which may get opened at this point. When
+      the socket was closed in ip_connect(), the log could get the same file
+      descriptor number as the socket. This naturally causes chaos. The fix is
+      not to close the socket in ip_connect(); the socket should be closed by
+      the function that creates it. There was only one place in the code where
+      this was missing, in the iplookup router, which I don't think anybody now
