Change log file for Exim from version 4.21
-------------------------------------------
+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).
+
+
Exim version 4.61
-----------------
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
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.
+
