+PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
+ syntactically invalid From: or Reply-to: line, and a filter used this to
+ generate an autoreply, and therefore failed to obtain an address for the
+ autoreply, Exim could try to deliver to a non-existent relative file
+ name, causing unrelated and misleading errors. What now happens is that
+ it logs this as a hard delivery error, but does not attempt to create a
+ bounce message.
+
+PH/11 The exinext utility has a -C option for testing purposes, but although
+ the given file was scanned by exinext itself; it wasn't being passed on
+ when Exim was called.
+
+PH/12 In the smtp transport, treat an explicit ECONNRESET error the same as
+ an end-of-file indication when reading a command response.
+
+PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
+ compiled. In many other places in Exim, IPv6 addresses are always
+ recognized, so I have changed this. It also means that IPv4 domain
+ literals of the form [IPV4:n.n.n.n] are now always recognized.
+
+PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
+ used if the router is not running as root, for example, when verifying at
+ ACL time, or when using -bh. The debugging output from this situation was
+ non-existent - all you got was a failure to exec. I have made two
+ changes:
+
+ (a) Failures to set uid/gid, the current directory, or a process leader
+ in a subprocess such as that created by queryprogram now generate
+ suitable debugging ouput when -d is set.
+
+ (b) The queryprogram router detects when it is not running as root,
+ outputs suitable debugging information if -d is set, and then runs
+ the subprocess without attempting to change uid/gid.
+
+PH/15 Minor change to Makefile for building test_host (undocumented testing
+ feature).
