64
25-Apr-2014 : Version 1.4
65
*) fix ENVID and ORCPT addition in SMTP transport
66
*) p was not moved to the end of the string. new content
67
added afterwards overwrites ENVID and/or ORCPT
68
*) change spool file format to be compatible with the
69
extensible format of exim 4 by prepending new values and
70
setting the extended bitmask accordingly
71
*) use SUPPORT_DSN_LEGACY=yes in Makefile to be able to read
72
the legacy format of older patches until all messages are out of queue.
73
*) change "dsn" boolean toggle to "dsn_advertise_hosts" to
74
be able to select who actually can use the extension
75
*) Add all RFC 3461 MUST fields to delivery-status section
76
*) convert xtext in ENVID
77
*) add all successful rcpts to ONE message instead of sending several messages
79
26-Apr-2014 : Version 1.5
81
*) fixed wrong order for ENVID
82
*) fixed wrong Final-Recipient value
83
*) af_ignore_failure is ignored for success reports
84
*) fixed DSN_LEGACY switch
86
*) added MIME "failure" reports
87
*) bounce_return_message is ignored (required by RFC)
88
*) in case RET= is defined we honor these values
89
otherwise bounce_return_body is honored.
90
*) bounce_return_size_limit is always honored.
91
*) message body intro and final text is ignored
92
*) do not send report if DSN flags say NO
93
*) added MIME "delay" reports
94
*) do not send report if DSN flags say NO
95
*) changed from SUPPORT_DSN to EXPERIMENTAL_DSN
96
*) updated documentation
98
01-May-2014 : Version 1.6
101
*) use text/rfc822-headers were applicable
102
*) fix NOTIFY=FAILURE
105
*) do not truncated MIME messages
106
*) if bounce_return_size_limit is smaller then the actual message
107
only the header is returned
108
*) if bounce_return_body or bounce_return_size_limit prevents Exim
109
from returning the requested (RET=FULL) body this fact is added
110
as X-Exim-DSN-Information Header
111
*) this also means that all of the last three parts of the "failure"
112
template are not used anymore
114
*) dsn_process switch removed
115
*) every router "processes" DSN by default
116
*) there is no possibilty to "gag" DSN anymore since this violates RFC
117
*) dsn_lasthop switch added for routers
118
*) if dsn_lasthop is set by a router it is handled as relaying to a
119
non DSN aware relay. success mails are sent if Exim successfully
120
delivers the message.
121
*) redirect routers always "act" as if dsn_lasthop is set
123
*) address_item.dsn_aware changed from uschar to int for easier handling.
126
*) Reporting-MTA: use smtp_active_hostname instead of qualify_domain from
130
*) removed support for EXPERIMENTAL_DSN_LEGACY for codebase inclusion
131
*) fixed build of exim_monitor tree
132
*) fixed late declaration of dsn_all_lasthop
