Change log file for Exim from version 4.21
-------------------------------------------
"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.
+ address.
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.
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."
+
+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.

A note about Exim versions 4.44 and 4.50
