Change log file for Exim from version 4.21
-------------------------------------------
27. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
support for a long time. Removed HAVE_SYS_VFS_H.
+28. Installed the latest version of exipick from John Jetmore.
+
+29. In an address list, if the pattern was not a regular expression, an empty
+ subject address (from a bounce message) matched only if the pattern was an
+ empty string. Non-empty patterns were not even tested. This was the wrong
+ because it is perfectly reasonable to use an empty address as part of a
+ database query. An empty address is now tested by patterns that are
+ lookups. However, all the other forms of pattern expect the subject to
+ contain a local part and a domain, and therefore, for them, an empty
+ address still always fails if the pattern is not itself empty.
+
+30. Exim went into a mad DNS loop when attempting to do a callout where the
+ host was specified on an smtp transport, and looking it up yielded more
+ than one IP address.
+
+31. Re-factored the code for checking spool and log partition space into a
+ function that finds that data and another that does the check. The former
+ is then used to implement four new variables: $spool_space, $log_space,
+ $spool_inodes, and $log_inodes.
+
+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) There is a new type, "mxh", which is like "mx" except that it returns
+ just the host names, not the priorities.
+
+ (3) It is now possible to give a list of domains (or IP addresses) to be
+ looked up.
+
+ (4) It is now possible to specify the separator character for use when
+ multiple records are returned.
+
+38. The dnslists ACL condition has been extended: it is now possible to supply
+ a list of IP addresses and/or domains to be looked up in a particular DNS
+ domain.
+
+39. Added log_selector=+queue_time_overall.
+
+40. When running the queue in the test harness, wait just a tad after forking a
+ delivery process, to get repeatability of debugging output.
+
