This may well have applied to all BSD + systems, as well as to others that have similar system calls. The broken + code found IPv4 interfaces correctly, but gave incorrect values for the + IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was + that it would not match correctly against @[] and not recognize the IPv6 + addresses as local. + +PH/02 The ipliteral router was not recognizing addresses of the form user@ + [ipv6:....] because it didn't know about the "ipv6:" prefix. + +PH/03 Added disable_ipv6. + +PH/04 Changed $reply_address to use the raw form of the headers instead of the + decoded form, because it is most often used to construct To: headers + lines in autoreplies, and the decoded form may well be syntactically + invalid. However, $reply_address has leading white space removed, and all + newlines turned into spaces so that the autoreply transport does not + grumble. + +PH/05 If group was specified without a user on a router, and no group or user + was specified on a transport, the group from the router was ignored. + +PH/06 Increased the number of ACL variables to 20 of each type, and arranged + for visible compile-time settings that can be used to change these + numbers, for those that want even more. Backwards compatibility with old + spool files has been maintained. However, going back to a previous Exim + release will lost any variables that are in spool files. + +PH/07 Two small changes when running in the test harness: increase delay when + passing a TCP/IP connection to a new process, in case the original + process has to generate a bounce, and remove special handling of + 127.0.0.2 (sic), which is no longer necessary. + +PH/08 Changed debug output of dbfn_open() flags from numbers to names, so as to + be the same on different OS. + +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). + + + Exim version 4.60 ----------------- @@ -194,9 +334,6 @@ TF/01 The control=submission/name=... option had a problem with syntax PH/05 Some modifications to the interface to the fake nameserver for the new testing suite. -PH/06 Add ${if def:sender_address {(envelope-from <$sender_address>)\n\t}} - into the default Received: header string. - Exim version 4.53
