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. + +PH/36 Now that the new test suite is complete, we can remove some of the + special code in Exim that was needed for the old test suite. For example, + sorting DNS records because real resolvers return them in an arbitrary + order. The new test suite's fake resolver always returns records in the + same order. + +PH/37 When running in the test harness, use -odi for submitted messages (e.g. + bounces) except when queue_only is set, to avoid logging races between + the different processes. + Exim version 4.60 -----------------
