See NewStuff for details. + +PH/01 When a transport filter timed out in a pipe delivery, and the pipe + command itself ended in error, the underlying message about the transport + filter timeout was being overwritten with the pipe command error. Now the + underlying error message should be appended to the second error message. + +TK/01 Fix poll() being unavailable on Mac OSX 10.2. + +PH/02 Reduce the amount of output that "make" produces by default. Full output + can still be requested. + +PH/03 The warning log line about a condition test deferring for a "warn" verb + was being output only once per connection, rather than after each + occurrence (because it was using the same function as for successful + "warn" verbs). This seems wrong, so I have changed it. + +TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that + it should not have, which might have caused a crash in the right + circumstances, but probably never did. + +PH/04 Installed a modified version of Tony Finch's patch to make submission + mode fix the return path as well as the Sender: header line, and to + add a /name= option so that you can make the user's friendly name appear + in the header line. + +TF/03 Added the control = fakedefer ACL modifier. + +TF/04 Added the ratelimit ACL condition. See NewStuff for details. Thanks to + Mark Lowes for thorough testing. + +TK/02 Rewrote SPF support to work with libspf2 versions >1.2.0. + +TK/03 Merged latest SRS patch from Miles Wilton. + +PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts + with the definition in sysexits.h (which is #included earlier). + Fortunately, Exim does not actually use EX_OK. The code used to try to + preserve the sysexits.h value, by assumimg that macro definitions were + scanned for macro replacements. I have been disabused of this notion, + so now the code just undefines EX_OK before #including unistd.h. + +PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout + in the smtp transport. When a block could not be written in a single + write() function, the timeout was being re-applied to each part-write. + This seems wrong - if the receiver was accepting one byte at a time it + would take for ever. The timeout is now adjusted when this happens. It + doesn't have to be particularly precise. + +TK/04 Added simple SPF lookup method in EXPERIMENTAL_SPF. See NewStuff for + details. Thanks to Chris Webb for the patch! + +PH/07 Added "fullpostmaster" verify option, which does a check to + without a domain if the check to fails. + +SC/01 Eximstats: added -xls and the ability to specify output files + (patch written by Frank Heydlauf). + +SC/02 Eximstats: use FileHandles for outputing results. + +SC/03 Eximstats: allow any combination of xls, txt, and html output. + +SC/04 Eximstats: fixed display of large numbers with -nvr option + +SC/05 Eximstats: fixed merging of reports with empty tables. + +SC/06 Eximstats: added the -include_original_destination flag + +SC/07 Eximstats: removed tabs and trailing whitespace. + +TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller. + +TK/06 MBOX spool code: Add real "From " MBOX separator line + so the .eml file is really in mbox format (even though + most programs do not really care). Patch from Alex Miller. + +TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers. + The latter is generated from $received_to and is only set if the + message has one envelope recipient. SA can use these headers, + obviously out-of-the-box. Patch from Alex Miller. + +PH/08 The ${def test on a variable was returning false if the variable's + value was "0", contrary to what the specification has always said! + The result should be true unless the variable is empty. + +PH/09 The syntax error of a character other than { following "${if + def:variable_name" (after optional whitespace) was not being diagnosed. + An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an + accidental colon was present, for example, could give incorrect results. + +PH/10 Tidied the code in a number of places where the st_size field of a stat() + result is used (not including appendfile, where other changes are about + to be made). + +PH/11 Upgraded appendfile so that quotas larger than 2G are now supported. + This involved changing a lot of size variables from int to off_t. It + should work with maildirs and everything. + +TK/08 Apply fix provided by Michael Haardt to prevent deadlock in case of + spamd dying while we are connected to it. + +TF/05 Fixed a ${extract error message typo reported by Jeremy Harris + + +PH/12 Applied Alex Kiernan's patch for the API change for the error callback + function for BDB 4.3. + +PH/13 Changed auto_thaw such that it does not apply to bounce messages. + +PH/14 Imported PCRE 6.0; this was more than just a trivial operation because + the sources for PCRE have been re-arranged and more files are now + involved. + +PH/15 The code I had for printing potentially long long variables in PH/11 + above was not the best (it lost precision). The length of off_t variables + is now inspected at build time, and an appropriate printing format (%ld + or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T + to be "long long int" or "long int". This is needed for the internal + formatting function string_vformat(). + +PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in + the configuration file to be ":syslog", then the script "guesses" where + the logs files are, rather than using the compiled in default. In our + case the guess is not the same as the compiled default, so the script + suddenly stopped working when I started to use syslog. The patch checks + to see if log_file_path is "". If so, it attempts to read it from exim + with no configuration file to get the compiled in version, before it + falls back to the previous guessing code." + +TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with + implementing BATV in an Exim configuration. See NewStuff for the gory + details. + +PH/17 Applied Michael Haardt's patch for HP-UX, affecting only the os.h and + Makefile that are specific to HP-UX. + +PH/18 If the "use_postmaster" option was set for a recipient callout together + with the "random" option, the postmaster address was used as the MAIL + FROM address for the random test, but not for the subsequent recipient + test. It is now used for both. + +PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The + patch removes a few documentation additions to RFC 3028, because the + latest draft now contains them. It adds the new en;ascii-case comparator + and a new error check for 8bit text in MIME parts. Comparator and + require names are now matched exactly. I enabled the subaddress + extension, but it is not well tested yet (read: it works for me)." + +PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to + rework some of the code of TK/09 above to avoid the hardwired use of + "%lld" and "long long". Replaced the call to snprintf() with a call to + string_vformat(). + +PH/21 Added some other messages to those in 4.51/PH/42, namely "All relevant MX + records point to non-existent hosts", "retry timeout exceeded", and + "retry time not reached for any host after a long failure period". + +PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with + experimental DomainKeys support: + + (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken. + (2) On an error such as an illegally used "control", the wrong name for + the control was given. + + These problems did NOT occur unless DomainKeys support was compiled. + +PH/23 Added daemon_startup_retries and daemon_startup_sleep. + +PH/24 Added ${if match_ip condition. + +PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints + databases so that it will be absolutely obvious if a crash occurs in the + DB library. This is a regular occurrence (often caused by mis-matched + db.h files). + +PH/26 Insert a lot of missing (void) casts for functions such as chown(), + chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were + picked up on a user's system that detects such things. There doesn't seem + to be a gcc warning option for this - only an attribute that has to be + put on the function's prototype. It seems that in Fedora Core 4 they have + set this on a number of new functions. No doubt there will be more in due + course. + +PH/27 If a dnslookup or manualroute router is set with verify=only, it need not + specify a transport. However, if an address that was verified by such a + router was the subject of a callout, Exim crashed because it tried to + read the rcpt_include_affixes from the non-existent transport. Now it + just assumes that the setting of that option is false. This bug was + introduced by 4.51/PH/31. + +PH/28 Changed -d+all to exclude +memory, because that information is very + rarely of interest, but it makes the output a lot bigger. People tend to + do -d+all out of habit. + +PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the + code in os-type was giving problems when libc.so lives in lib64, like on + x86_64 Fedora Core. + +PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These + aren't the modern standard, and it seems that some systems' include files + don't always have them. Exim was already checking for some of the newer + ones like T_AAAA, and defining it itself. I've added checks for all the + record types that Exim uses. + +PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was + not automatically generating a new one, as it is supposed to. This + prevented TLS from working. If the file did exist, but contained invalid + data, a new version was generated, as expected. It was only the case of a + non-existent file that was broken. + +TK/10 Domainkeys: Fix a bug in verification that caused a crash in conjunction + with a change in libdomainkeys > 0.64. + +TK/11 Domainkeys: Change the logic how the "testing" policy flag is retrieved + from DNS. If the selector record carries the flag, it now has + precedence over the domain-wide flag. + +TK/12 Cleared some compiler warnings related to SPF, SRS and DK code. + +PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as + the use of a port name that isn't defined in /etc/services) occurred, the + message was deferred as in a normal delivery, and thus remained on the + spool, instead of being failed because of the mua_wrapper setting. This + is now fixed, and I tidied up some of the mua_wrapper messages at the + same time. + +SC/08 Eximstats: whilst parsing the mainlog(s), store information about + the messages in a hash of arrays rather than using individual hashes. + This is a bit cleaner and results in dramatic memory savings, albeit + at a slight CPU cost. + +SC/09 Eximstats: added the -show_rt and the -show_dt flags + as requested by Marc Sherman. + +SC/10 Eximstats: added histograms for user specified patterns as requested + by Marc Sherman. + +SC/11 Eximstats: v1.43 - bugfix for pattern histograms with -h0 specified. + + Exim version 4.51 ----------------- @@ -266,6 +509,27 @@ PH/42 Exim no longer gives details of delivery errors for specific addresses in PH/43 $value is now also set for the "else" part of a ${run expansion. +PH/44 Applied patch from the Sieve maintainer: "The vacation draft is still + being worked on, but at least Exim now implements the latest version to + play with." + +PH/45 In a pipe transport, although a timeout while waiting for the pipe + process to complete was treated as a delivery failure, a timeout while + writing the message to the pipe was logged, but erroneously treated as a + successful delivery. Such timeouts include transport filter timeouts. For + consistency with the overall process timeout, these timeouts are now + treated as errors, giving rise to delivery failures by default. However, + there is now a new Boolean option for the pipe transport called + timeout_defer, which, if set TRUE, converts the failures into defers for + both kinds of timeout. A transport filter timeout is now identified in + the log output. + +PH/46 The "scripts/Configure-config.h" script calls "make" at one point. On + systems where "make" and "gmake" are different, calling "gmake" at top + level broke things. I've arranged for the value of $(MAKE) to be passed + from the Makefile to this script so that it can call the same version of + "make". + A note about Exim versions 4.44 and 4.50 ----------------------------------------
