+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.
