 Change log file for Exim from version 4.21

     is then used to implement four new variables: $spool_space, $log_space,

+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.
+
+36. The table in the code that translates DNS record types into text (T_A to
+    "A" for instance) was missing entries for NS and CNAME. It is just possible
+    that this could have caused confusion if both these types were looked up
+    for the same domain, because the text type is used as part of Exim's
+    per-process caching. But the chance of anyone hitting this buglet seems
+    very small.
+
+37. The dnsdb lookup has been extended in a number of ways.
+
+    (1) There is a new type, "zns", which walks up the domain tree until it
+        finds some nameserver records. It should be used with care.
+
+    (2) It is now possible to give a list of domains (or IP addresses) to be
+        looked up.
+
+    (3) It is now possible to specify the separator character for use when
+        multiple records are returned.
