Change log file for Exim from version 4.21
-------------------------------------------
PH/09 Moved a debug statement in filter processing to avoid a race problem when
testing.
+JJ/01 exipick: fixed bug where -b (brief) output option showed "Vars:"
+ whether --show-vars was specified or not
+
+JJ/02 exipick: Added support for new ACL variable spool format introduced
+ in 4.61-PH/06
+
+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).
+
+PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
+ additional section of a DNS packet that returns MX or SRV records.
+ Instead, it always explicitly searches for A/AAAA records. This avoids
+ major problems that occur when a DNS server includes only records of one
+ type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
+ fixed another bug: if SRV records were looked up and the corresponding
+ address records were *not* found in the additional section, the port
+ values from the SRV records were lost.
+
+PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
+ using the correct key (the original address) when searching the retry
+ rules in order to find which one to use for generating the retry hint.
+
+PH/18 If quota_warn_message contains a From: header, Exim now refrains from
+ adding the default one. Similarly, if it contains a Reply-To: header, the
+ errors_reply_to option, if set, is not used.
+
+PH/19 When calculating a retry time, Exim used to measure the "time since
+ failure" by looking at the "first failed" field in the retry record. Now
+ it does not use this if it is later than than the arrival time of the
+ message. Instead it uses the arrival time. This makes for better
+ behaviour in cases where some deliveries succeed, thus re-setting the
+ "first failed" field. An example is a quota failure for a huge message
+ when small messages continue to be delivered. Without this change, the
+ "time since failure" will always be short, possible causing more frequent
+ delivery attempts for the huge message than are intended.
+
+PH/20 Added $auth1, $auth2, $auth3 to contain authentication data (as well as
+ $1, $2, $3) because the numerical variables can be reset during some
+ expansion items (e.g. "match"), thereby losing the authentication data.
+
+PH/21 Make -bV show the size of off_t variables so that the test suite can
+ decide whether to run tests for quotas > 2G.
+
+PH/22 Test the values given for quota, quota_filecount, quota_warn_threshold,
+ mailbox_size, and mailbox_filecount in the appendfile transport. If a
+ filecount value is greater than 2G or if a quota value is greater than 2G
+ on a system where the size of off_t is not greater than 4, a panic error
+ is given.
+
+PH/23 When a malformed item such as 1.2.3/24 appears in a host list, it can
+ never match. The debug and -bh output now contains an explicit error
+ message indicating a malformed IPv4 address or mask.
+
+PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
+ 1.2.3.4 without a mask. Now it is not recognized as an IP address, and
+ PH/23 above applies.
+
+PH/25 Do not write to syslog when running in the test harness. The only
+ occasion when this arises is a failure to open the main or panic logs
+ (for which there is an explicit test).
+
+PH/26 Added the /no_tell option to "control=freeze".
+
+PH/27 If a host name lookup failed very early in a connection, for example, if
+ the IP address matched host_lookup and the reverse lookup yielded a name
+ that did not have a forward lookup, an error message of the form "no IP
+ address found for host xxx.xxx.xxx (during SMTP connection from NULL)"
+ could be logged. Now it outputs the IP address instead of "NULL".
+
+PH/28 An enabling patch from MH: add new function child_open_exim2() which
+ allows the sender and the authenticated sender to be set when
+ submitting a message from within Exim. Since child_open_exim() is
+ documented for local_scan(), the new function should be too.
+
+PH/29 In GnuTLS, a forced expansion failure for tls_privatekey was not being
+ ignored. In both GnuTLS and OpenSSL, an expansion of tls_privatekey that
+ results in an empty string is now treated as unset.
+
+PH/30 Fix eximon buffer overflow bug (Bugzilla #73).
+
+PH/31 Added sender_verify_fail logging option.
+
+PH/32 In November 2003, the code in Exim that added an empty Bcc: header when
+ needed by RFC 822 but not by RFC 2822 was commented out. I have now
+ tidied the source and removed it altogether.
+
+PH/33 When a queue run was abandoned because the load average was too high, a
+ log line was always written; now it is written only if the queue_run log
+ selector is set. In addition, the log line for abandonment now contains
+ information about the queue run such as the pid. This is always present
+ in "start" and "stop" lines but was omitted from the "abandon" line.
+
+PH/34 Omit spaces between a header name and the colon in the error message that
+ is given when verify = headers_syntax fails (if there are lots of them,
+ the message gets confusing).
+
+PH/35 Change the default for dns_check_names_pattern to allow slashes within
+ names, as there are now some PTR records that contain slashes. This check
+ is only to protect against broken name servers that fall over on strange
+ characters, so the fact that it applies to all lookups doesn't matter.
+
Exim version 4.60
