See + doc/experimental-spec.txt for details. (http://domainkeys.sf.net) + +TK/02 Fix ACL "control" statement not being available in MIME ACL. + +TK/03 Fix ACL "regex" condition not being available in MIME ACL. + +PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used + to test Sieve filters that use "vacation". + +PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch + that changes the way the GnuTLS parameters are stored in the cache file. + The new format can be generated externally. For backward compatibility, + if the data in the cache doesn't make sense, Exim assumes it has read an + old-format file, and it generates new data and writes a new file. This + means that you can't go back to an older release without removing the + file. + +PH/03 A redirect router that has both "unseen" and "one_time" set does not + work if there are any delivery delays because "one_time" forces the + parent to be marked "delivered", so its unseen clone is never tried + again. For this reason, Exim now forbids the simultaneous setting of + these two options. + +PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are + redirected to themselves ("homonym" addresses). Read the long ChangeLog + entry if you want to know the details. The fix, however, neglected to + consider the case when local delivery batching is involved. The test for + "previously delivered" was not happening when checking to see if an + address could be batched with a previous (undelivered) one; under + certain circumstances this could lead to multiple deliveries to the same + address. A one-line patch to add the appropriate test fixes the bug. + +PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T + in its include files, and this causes problems building Exim. + +PH/06 A number of "verify =" ACL conditions have no options (e.g. verify = + header_syntax) but Exim was just ignoring anything given after a slash. + In particular, this caused confusion with an attempt to use "verify = + reverse_host_lookup/defer_ok". An error is now given when options are + supplied for verify items that do not have them. (Maybe reverse_host_ + lookup should have a defer_ok option, but that's a different point.) + +PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as + defined by RFC 821) to 2048, because there were problems with some AUTH + commands, and RFC 1869 says the size should be increased for extended + SMTP commands that take arguments. + +PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony + Finch). + +PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an + "unknown" error; now it says that the functionality isn't in the binary. + +PH/10 Added a nasty fudge to try to recognize and flatten LDAP passwords in + an address' error message when a string expansion fails (syntax or + whatever). Otherwise not only does the password appear in the log, it may + also be put in a bounce message. + +PH/11 Installed exipick version 20050225.0 from John Jetmore. + +PH/12 If the last host in a fallback_hosts list was multihomed, only the first + of its addresses was ever tried. (Bugzilla bug #2.) + +PH/13 If "headers_add" in a transport didn't end in a newline, Exim printed + the result incorrectly in the debug output. (It correctly added a newline + to what was transported.) + +TF/01 Added $received_time. + +PH/14 Modified the default configuration to add an acl_smtp_data ACL, with + commented out examples of how to interface to a virus scanner and to + SpamAssassin. Also added commented examples of av_scanner and + spamd_address settings. + +PH/15 Further to TK/02 and TK/03 above, tidied up the tables of what conditions + and controls are allowed in which ACLs. There were a couple of minor + errors. Some of the entries in the conditions table (which is a table of + where they are NOT allowed) were getting very unwieldy; rewrote them as a + negation of where the condition IS allowed. + +PH/16 Installed updated OS/os.c-cygwin from the Cygwin maintainer. + +PH/17 The API for radiusclient changed at release 0.4.0. Unfortunately, the + header file does not have a version number, so I've had to invent a new + value for RADIUS_LIB_TYPE, namely "RADIUSCLIENTNEW" to request the new + API. The code is untested by me (my Linux distribution still has 0.3.2 of + radiusclient), but it was contributed by a Radius user. + +PH/18 Installed Lars Mainka's patch for the support of CRL collections in + files or directories, for OpenSSL. + +PH/19 When an Exim process that is running as root has to create an Exim log + file, it does so in a subprocess that runs as exim:exim so as to get the + ownership right at creation (otherwise, other Exim processes might see + the file with the wrong ownership). There was no test for failure of this + fork() call, which would lead to the process getting stuck as it waited + for a non-existent subprocess. Forks do occasionally fail when resources + run out. I reviewed all the other calls to fork(); they all seem to check + for failure. + +PH/20 When checking for unexpected SMTP input at connect time (before writing + the banner), Exim was not dealing correctly with a non-positive return + from the read() function. If the client had disconnected by this time, + the result was a log entry for a synchronization error with an empty + string after "input=" when read() returned zero. If read() returned -1 + (an event I could not check), uninitialized data bytes were printed. + There were reports of junk text (parts of files, etc) appearing after + "input=". + +PH/21 Added acl_not_smtp_mime to allow for MIME scanning for non-SMTP messages. + +PH/22 Added support for macro redefinition, and (re)definition in between + driver and ACL definitions. + +PH/23 The cyrus_sasl authenticator was expanding server_hostname, but then + forgetting to use the resulting value; it was using the unexpanded value. + +PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it + hadn't been configured. The fix is from Juergen Kreileder, who + understands it better than I do: + + "Here's what I see happening with three configured cyrus_sasl + authenticators configured (plain, login, cram-md5): + + On startup auth_cyrus_sasl_init() gets called for each of these. + This means three calls to sasl_listmech() without a specified mech_list. + => SASL tests which mechs of all available mechs actually work + => three warnings about OTP not working + => the returned list contains: plain, login, cram-md5, digest-md5, ... + + With the patch, sasl_listmech() also gets called three times. But now + SASL's mech_list option is set to the server_mech specified in the the + authenticator. Or in other words, the answer from sasl_listmech() + gets limited to just the mech you're testing for (which is different + for each call.) + => the return list contains just 'plain' or 'login', 'cram-md5' or + nothing depending on the value of ob->server_mech. + + I've just tested the patch: Authentication still works fine, + unavailable mechs specified in the exim configuration are still + caught, and the auth.log warnings about OTP are gone." + + A note about Exim versions 4.44 and 4.50 ---------------------------------------- @@ -389,6 +536,11 @@ Exim version 4.50 83.
