ChangeLog
---------
14-Apr-2006 : Changed subject to "Delivery Status Notification"
17-May-2006 : debug_printf in spool-in.c were not wrapped with #ifndef COMPILE_UTILITY
thanks to Andrey J. Melnikoff for this information
12-Sep-2006 : Now supports Exim 4.63
12-Sep-2006 : src/EDITME did not include the #define SUPPORT_DSN as stated
in the documentation, this has now been corrected
thanks to Robert Kehl for this information
28-Jul-2008 : New version for exim 4.69 released.
02-Jul-2010 : New version for exim 4.72 released.
25-Apr-2014 : Version 1.4
*) fix ENVID and ORCPT addition in SMTP transport
*) p was not moved to the end of the string. new content
added afterwards overwrites ENVID and/or ORCPT
*) change spool file format to be compatible with the
extensible format of exim 4 by prepending new values and
setting the extended bitmask accordingly
*) use SUPPORT_DSN_LEGACY=yes in Makefile to be able to read
the legacy format of older patches until all messages are out of queue.
*) change "dsn" boolean toggle to "dsn_advertise_hosts" to
be able to select who actually can use the extension
*) Add all RFC 3461 MUST fields to delivery-status section
*) convert xtext in ENVID
*) add all successful rcpts to ONE message instead of sending several messages
26-Apr-2014 : Version 1.5
fixes:
*) fixed wrong order for ENVID
*) fixed wrong Final-Recipient value
*) af_ignore_failure is ignored for success reports
*) fixed DSN_LEGACY switch
improvements:
*) added MIME "failure" reports
*) bounce_return_message is ignored (required by RFC)
*) in case RET= is defined we honor these values
otherwise bounce_return_body is honored.
*) bounce_return_size_limit is always honored.
*) message body intro and final text is ignored
*) do not send report if DSN flags say NO
*) added MIME "delay" reports
*) do not send report if DSN flags say NO
*) changed from SUPPORT_DSN to EXPERIMENTAL_DSN
*) updated documentation
01-May-2014 : Version 1.6
fixes:
*) code cleanup
*) use text/rfc822-headers were applicable
*) fix NOTIFY=FAILURE
improvements:
*) do not truncated MIME messages
*) if bounce_return_size_limit is smaller then the actual message
only the header is returned
*) if bounce_return_body or bounce_return_size_limit prevents Exim
from returning the requested (RET=FULL) body this fact is added
as X-Exim-DSN-Information Header
*) this also means that all of the last three parts of the "failure"
template are not used anymore
*) dsn_process switch removed
*) every router "processes" DSN by default
*) there is no possibility to "gag" DSN anymore since this violates RFC
*) dsn_lasthop switch added for routers
*) if dsn_lasthop is set by a router it is handled as relaying to a
non DSN aware relay. success mails are sent if Exim successfully
delivers the message.
*) redirect routers always "act" as if dsn_lasthop is set
*) address_item.dsn_aware changed from uschar to int for easier handling.
02-May-2014 : fixes:
*) Reporting-MTA: use smtp_active_hostname instead of qualify_domain from
original patch.
20-May-2014 : fixes:
*) removed support for EXPERIMENTAL_DSN_LEGACY for codebase inclusion
*) fixed build of exim_monitor tree
*) fixed late declaration of dsn_all_lasthop
