 Change log file for Exim from version 4.21
 -------------------------------------------
@@ -64,6 +64,51 @@ PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
       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:
+      (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).
