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.
+
+
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
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
