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.

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." + +PH/25 When debugging is enabled, the contents of the command line are added + to the debugging output, even when log_selector=+arguments is not + specified. + +PH/26 Change scripts/os-type so that when "uname -s" returns just "GNU", the + answer is "GNU", and only if the return is "GNU/something" is the answer + "Linux". + +PH/27 $acl_verify_message is now set immediately after the failure of a + verification in an ACL, and so is available in subsequent modifiers. In + particular, the message can be preserved by coding like this: + + warn !verify = sender + set acl_m0 = $acl_verify_message + + Previously, $acl_verify_message was set only while expanding "message" + and "log_message" when a very denied access. + +PH/28 Modified OS/os.c-Linux with + + -#ifndef OS_LOAD_AVERAGE + +#if !defined(OS_LOAD_AVERAGE) && defined(__linux__) + + to make Exim compile on kfreebsd-gnu.

Two addresses routed to the same list of hosts; + . First host does not offer TLS; + . First host accepts first address; + . First host gives temporary error to second address; + . Second host offers TLS and a TLS session is established; + . Second host accepts second address. + Exim incorrectly logged both deliveries with the TLS parameters (cipher + and peerdn, if requested) that were in fact used only for the second + address. + +PH/31 When doing a callout as part of verifying an address, Exim was not paying + attention to any local part prefix or suffix that was matched by the + router that accepted the address. It now behaves in the same way as it + does for delivery: the affixes are removed from the local part unless + rcpt_include_affixes is set on the transport. + +PH/32 Add the sender address, as F=<...>, to the log line when logging a + timeout during the DATA phase of an incoming message. + + A note about Exim versions 4.44 and 4.50 ----------------------------------------
