This + is correct for most verifications, but it is not correct for a recipient + verification with use_sender or use_postmaster set, because in that case + the callout does not use MAIL FROM:<>. Exim now distinguishes the special + case of MAIL FROM:<> rejection from other early rejections (e.g. + rejection of HELO). When verifying a recipient using a non-null MAIL + address, the cache is ignored if it shows MAIL FROM:<> rejection. + Whatever the result of the callout, the value of the domain cache is + left unchanged (for any other kind of callout, getting as far as trying + RCPT means that the domain itself is ok). + +PH/02 Tidied a number of unused variable and signed/unsigned warnings that + gcc 4.1.1 threw up. + +PH/03 On Solaris, an unexpectedly close socket (dropped connection) can + manifest itself as EPIPE rather than ECONNECT. When tidying away a + session, the daemon ignores ECONNECT errors and logs others; it now + ignores EPIPE as well. + +PH/04 Applied Nico Erfurth's refactoring patch to tidy up mime.c + (quoted-printable decoding). + + +Exim version 4.63 +----------------- + +SC/01 Use a glob alias rather than an array ref in eximstats generated + parser. This improves both readability and performance. + +SC/02 Collect SpamAssassin and rejection statistics in eximstats. + Don't display local sender or destination tables in eximstats unless + there is data to show. + Added average volumes into the eximstats top table text output. + +SC/03 Collect data on the number of addresses (recipients) as well + as the number of messages in eximstats. + +TF/01 Correct an error in the documentation for the redirect router. Exim + does (usually) call initgroups() when daemonizing. + +TF/02 Call initgroups() when dropping privilege in exim.c, so that Exim runs + with consistent privilege compared to when running as a daemon. + +TF/03 Note in the spec that $authenticated_id is not set for local + submissions from trusted users. + +TF/04 The ratelimit per_rcpt option now works correctly in acl_not_smtp. + Thanks to Dean Brooks for the patch. + +TF/05 Make it easier to get SMTP authentication and TLS/SSL support working + by adding some example configuration directives to the default + configuration file. A little bit of work is required to uncomment the + directives and define how usernames and passwords are checked, but + there is now a framework to start from. + +PH/01 Added #define LDAP_DEPRECATED 1 to ldap.c because some of the "old" + functions that Exim currently uses aren't defined in ldap.h for OpenLDAP + without this. I don't know how relevant this is to other LDAP libraries. + +PH/02 Add the verb name to the "unknown ACL verb" error. + +PH/03 Magnus Holmgren's patch for filter_prepend_home. + +PH/03 Fixed Bugzilla #101: macro definition between ACLs doesn't work. + +PH/04 Applied Magnus Holmgren's patch to fix Bugzilla #98: transport's home + directory not expanded when it should be if an expanded home directory + was set for the address (which is overridden by the transport). + +PH/05 Applied Alex Kiernan's patch to fix Bugzilla #99: a problem with + libradius. + +PH/06 Added acl_not_smtp_start, based on Johannes Berg's patch, and set the + bit to forbid control=suppress_local_fixups in the acl_not_smtp ACL, + because it is too late at that time, and has no effect. + +PH/07 Changed ${quote_pgsql to quote ' as '' instead of \' because of a + security issue with \' (bugzilla #107). I could not use the + PQescapeStringConn() function, because it needs a PGconn value as one of + its arguments. + +PH/08 When testing addresses using -bt, indicate those final addresses that + are duplicates that would not cause an additional delivery. At least one + person was confused, thinking that -bt output corresponded to deliveries. + (Suppressing duplicates isn't a good idea as you lose the information + about possibly different redirections that led to the duplicates.) + +PH/09 Applied patch from Erik to use select() instead of poll() in spam.c on + systems where poll() doesn't work, in particular OS X. + +PH/10 Added more information to debugging output for retry time not reached. + +PH/11 Applied patch from Arkadiusz Miskiewicz to apply a timeout to read + operations in malware.c. + +PH/12 Applied patch from Magnus Holmgren to include the "h" tag in Domain Keys + signatures. + +PH/13 If write_rejectlog was set false when logging was sent to syslog with + syslog_duplication set false, log lines that would normally be written + both the the main log and to the reject log were not written to syslog at + all. + +PH/14 In the default configuration, change the use of "message" in ACL warn + statements to "add_header". + +PH/15 Diagnose a filter syntax error for "seen", "unseen", or "noerror" if not + not followed by a command (e.g. "seen endif"). + +PH/16 Recognize SMTP codes at the start of "message" in ACLs and after :fail: + and :defer: in a redirect router. Add forbid_smtp_code to suppress the + latter. + +PH/17 Added extra conditions to the default value of delay_warning_condition + so that it is now: + + ${if or { \ + { !eq{$h_list-id:$h_list-post:$h_list-subscribe:}{} } \ + { match{$h_precedence:}{(?i)bulk|list|junk} } \ + { match{$h_auto-submitted:}{(?i)auto-generated|auto-replied} } \ + }{no}{yes}} + + The Auto-Submitted: and various List- headers are standardised, whereas I + don't think Precedence: ever was. + +PH/18 Refactored debugging code in route_finduser() to show more information, + in particular, the error code if getpwnam() issues one. + +PH/19 Added PQsetClientEncoding(conn, "SQL_ASCII") to the pgsql code module. + This is apparently needed in addition to the PH/07 change above to avoid + any possible encoding problems. + +PH/20 Perl can change the locale. Exim was resetting it after a ${perl call, + but not after initializing Perl. + +PH/21 Added a call to PQsetNoticeProcessor() to catch pgsql "notices" and + output them only if debugging. By default they are written stderr, + apparently, which is not desirable. + +PH/22 Added Alain Williams' LDAP patch to support setting REFERRALS=off on + queries. + +JJ/01 exipick: added --reverse (and -R synonym), --random, --size, --sort and + --not options + +JJ/02 exipick: rewrote --help documentation to hopefully make more clear. + +PH/23 Made -oMaa and -oMt work with -bh and -bs to pretend the connection is + authenticated or an ident call has been made. Suppress the default + values for $authenticated_id and $authenticated_sender (but permit -oMai + and -oMas) when testing with -bh. + +PH/24 Re-jigged the order of the tests in the default configuration so that the + tests for valid domains and recipients precede the DNS black list and CSA + tests, on the grounds that those ones are more expensive. + +PH/25 Exim was not testing for a space following SMTP commands such as EHLO + that require one. Thus, EHLORHUBARB was interpreted as a valid command. + This bug exists in every version of Exim that I still have, right back to + 0.12. + +PH/26 (n)wildlsearch lookups are documented as being done case-insensitively. + However, an attempt to turn on case-sensitivity in a regex key by + including (?-i) didn't work because the subject string was already + lowercased, and the effects were non-intuitive. It turns out that a + one-line patch can be used to allow (?-i) to work as expected. + + +Exim version 4.62 +----------------- + +TF/01 Fix the add_header change below (4.61 PH/55) which had a bug that (amongst + other effects) broke the use of negated acl sub-conditions. + +PH/01 ${readsocket now supports Internet domain sockets (modified John Jetmore + patch). + +PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow". + "Deny" causes Exim to reject the incoming connection with a 554 error. + Unfortunately, if there is a major crisis, such as a disk failure, + tcp-wrappers gives "deny", whereas what one would like would be some + kind of temporary error. A kludge has been added to help with this. + Before calling hosts_ctl(), errno is set zero. If the result is "deny", a + 554 error is used if errno is still zero or contains ENOENT (which occurs + if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a + 451 error is used. + +PH/03 Add -lutil to the default FreeBSD LIBS setting. + +PH/04 Change PH/19 for 4.61 was too wide. It should not be applied to host + errors. Otherwise a message that provokes a temporary error (when other + messages do not) can cause a whole host to time out. + +PH/05 Batch deliveries by appendfile and pipe transports did not work when the + addresses were routed directly to files or pipes from a redirect router. + File deliveries just didn't batch; pipe deliveries might have suffered + odd errors. + +PH/06 A failure to get a lock for a hints database would erroneously always say + "Failed to get write lock", even when it was really a read lock. + +PH/07 The appendfile transport was creating MBX lock files with a fixed mode + of 0600. This has been changed to use the value of the lockfile_mode + option (which defaults to 0600). + +PH/08 Applied small patch from the Sieve maintainer. + +PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash + folder from quota calculations, a direct delivery into this folder messed + up the contents of the maildirsize file. This was because the regex was + used only to exclude .Trash (or whatever) when the size of the mailbox + was calculated. There was no check that a delivery was happening into an + excluded directory. This bug has been fixed by ignoring all quota + processing for deliveries into excluded directories. + +PH/10 Added the maildirfolder_create_regex option to appendfile. + + +Exim version 4.61 +----------------- + +PH/01 The code for finding all the local interface addresses on a FreeBSD + system running IPv6 was broken. 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. + [Note: This change was subsequently modified - see PH/04 for 4.62.] + +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. + +PH/38 Panic-die if .include specifies a non-absolute path. + +PH/39 A tweak to the "H" retry rule from its user. + +JJ/03 exipick: Removed parentheses from 'next' and 'last' calls that specified + a label. They prevented compilation on older perls. + +JJ/04 exipick: Refactored code to prevent implicit split to @_ which caused + a warning to be raised on newish perls. + +JJ/05 exipick: Fixed bug where -bpc always showed a count of all messages + on queue. Changes to match documented behaviour of showing count of + messages matching specified criteria. + +PH/40 Changed the default ident timeout from 30s to 5s. + +PH/41 Added support for the use of login_cap features, on those BSD systems + that have them, for controlling the resources used by pipe deliveries. + +PH/42 The content-scanning code uses fopen() to create files in which to put + message data. Previously it was not paying any attention to the mode of + the files. Exim runs with umask(0) because the rest of the code creates + files with open(), and sets the required mode explicitly. Thus, these + files were ending up world-writeable. This was not a big issue, because, + being within the spool directory, they were not world-accessible. I have + created a function called modefopen, which takes an additional mode + argument. It sets umask(777), creates the file, chmods it to the required + mode, then resets the umask. All the relevant calls to fopen() in the + content scanning code have been changed to use this function. + +PH/43 If retry_interval_max is set greater than 24 hours, it is quietly reset + to 24 hours. This avoids potential overflow problems when processing G + and H retry rules. I suspect nobody ever tinkers with this value. + +PH/44 Added STRIP_COMMAND=/usr/bin/strip to the FreeBSD Makefile. + +PH/45 When the plaintext authenticator is running as a client, the server's + challenges are checked to ensure they are valid base64 strings. By + default, the authentication attempt is cancelled if an invalid string is + received. Setting client_ignore_invalid_base64 true ignores these errors. + The decoded challenge strings are now placed in $auth1, $auth2, etc. as + they are received. Thus, the responses can be made to depend on the + challenges. If an invalid string is ignored, an empty string is placed in + the variable. + +PH/46 Messages that are created by the autoreply transport now contains a + References: header, in accordance with RFCs 2822 and 3834. + +PH/47 Added authenticated_sender_force to the smtp transport. + +PH/48 The ${prvs expansion was broken on systems where time_t was long long. + +PH/49 Installed latest patch from the Sieve maintainer. + +PH/50 When an Exim quota was set without a file count quota, and mailbox_size + was also set, the appendfile transport was unnecessarily scanning a + directory of message files (e.g. for maildir delivery) to find the count + of files (along with the size), even though it did not need this + information. It now does the scan only if it needs to find either the + size of the count of files. + +PH/51 Added ${time_eval: to convert Exim time strings into seconds. + +PH/52 Two bugs concerned with error handling when the smtp transport is + used in LMTP mode: + + (i) Exim was not creating retry information for temporary errors given + for individual recipients after the DATA command when the smtp transport + was used in LMTP mode. This meant that they could be retried too + frequently, and not timed out correctly. + + (ii) Exim was setting the flag that allows error details to be returned + for LMTP errors on RCPT commands, but not for LMTP errors for individual + recipients that were returned after the DATA command. + +PH/53 This is related to PH/52, but is more general: for any failing address, + when detailed error information was permitted to be returned to the + sender, but the error was temporary, then after the final timeout, only + "retry timeout exceeded" was returned. Now it returns the full error as + well as "retry timeout exceeded". + +PH/54 Added control=allow_auth_unadvertised, as it seems there are clients that + do this, and (what is worse) MTAs that accept it. + +PH/55 Added the add_header modified to ACLs. The use of "message" with "warn" + will now be deprecated. + +PH/56 New os.c-cygwin from the Cygwin maintainer. + +JJ/06 exipick: added --unsorted option to allow unsorted output in all output + formats (previously only available in exim formats via -bpr, -bpru, + and -bpra. Now also available in native and exiqgrep formats) + +JJ/07 exipick: added --freeze and --thaw options to allow faster interaction + with very large, slow to parse queues + +JJ/08 exipick: added ! as generic prefix to negate any criteria format + +JJ/09 exipick: miscellaneous performance enhancements (~24% improvements) + +PH/57 Tidies in SMTP dialogue display in debug output: (i) It was not showing + responses to authentication challenges, though it was showing the + challenges; (ii) I've removed the CR characters from the debug output for + SMTP output lines. + +PH/58 Allow for the insertion of a newline as well as a space when a string + is turned into more than one encoded-word during RFC 2047 encoding. The + Sieve code now uses this. + +PH/59 Added the following errors that can be detected in retry rules: mail_4xx, + data_4xx, lost_connection, tls_required. + +PH/60 When a VRFY deferred or FAILED, the log message rather than the user + message was being sent as an SMTP response. + +PH/61 Add -l and -k options to exicyclog. + +PH/62 When verifying, if an address was redirected to one new address, so that + verification continued, and the new address failed or deferred after + having set something in $address_data, the value of $address_data was not + passed back to the ACL. This was different to the case when no + redirection occurred. The value is now passed back in both cases. + +PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to + HAVE_SETCLASSRESOURCES because there are different APIs in use that all + use login_cap.h, so on its own it isn't the distinguishing feature. The + new name refers directly to the setclassresources() function. + +PH/65 Added configuration files for NetBSD3. + +PH/66 Updated OS/Makefile-HP-UX for gcc 4.1.0 with HP-UX 11. + +PH/67 Fixed minor infelicity in the sorting of addresses to ensure that IPv6 + is preferred over IPv4. + +PH/68 The bounce_return_message and bounce_return_body options were not being + honoured for bounces generated during the reception of non-SMTP messages. + In particular, this applied to messages rejected by the ACL. This bug has + been fixed. However, if bounce_return_message is true and bounce_return_ + body is false, the headers that are returned for a non-SMTP message + include only those that have been read before the error was detected. + (In the case of an ACL rejection, they have all been read.) + +PH/69 The HTML version of the specification is now built in a directory called + spec_html instead of spec.html, because the latter looks like a path with + a MIME-type, and this confuses some software. + +PH/70 Catch two compiler warnings in sieve.c. + +PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The + function verify_get_ident() calls ip_connect() to connect a socket, but + if the "connect()" function timed out, ip_connect() used to close the + socket. However, verify_get_ident() also closes the socket later, and in + between Exim writes to the log, which may get opened at this point. When + the socket was closed in ip_connect(), the log could get the same file + descriptor number as the socket. This naturally causes chaos. The fix is + not to close the socket in ip_connect(); the socket should be closed by + the function that creates it. There was only one place in the code where + this was missing, in the iplookup router, which I don't think anybody now + uses, but I've fixed it anyway. + +PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as + well as to direct DNS lookups. Otherwise the handling of names in host + lists is inconsistent and therefore confusing. + + Exim version 4.60 ----------------- @@ -120,6 +702,52 @@ PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to PH/11 Added "${if def:sender_address {(envelope-from <$sender_address>)\n\t}}" to the default Received: header definition. +PH/12 Added log selector acl_warn_skipped (default on). + +PH/13 After a successful wildlsearch lookup, discard the values of numeric + variables because (a) they are in the wrong storage pool and (b) even if + they were copied, it wouldn't work properly because of the caching. + +PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length + checking when decoding.
