LIBDK: Copy the library options structure from libdkim.
LIBDK: Add dk_close().
LIBDK: Feature request #SF1872270: Rename parameters called "new"

_FFR_REPORTINFO
0.5.0 2007/04/10
Copy several enhancements from the latest dkim-milter update:
o Support for 8.14 (milter v2) and the leading space patch from
dkim-milter.
o Fixes/enhancements under POPAUTH.
o Pass the correct length variable to RSA_sign() so that
the value returned is sane on 64-bit platforms.
o _FFR_ANTICIPATE_SENDMAIL_MUNGE
o Feature request #SF1497801: _FFR_QUARANTINE
Fix bug #SF1541450: Correct header selection in dk_hdrsigned().
Reported by Mark Martinec.
LIBDK: Fix bug #SF1537918: Add dk_geterror() to retrieve additional
diagnostic data from the API when a function call returns
DK_STAT_INTERNAL or something else whose cause isn't
readily apparent. Copied from libdkim.
LIBAR: Block signals that should be caught and handled elsewhere,
such as in libmilter.
0.4.2 2007/03/13
Fix bug #SF1509093, SF1611082: Set group ID as well as user ID when
"-u" is used on the command line. Patch from Vincent
Rivellino.
Fix bug #SF1514447: Re-query for the job ID in mlfi_eom() to
accomodate postfix's milter implementation. Copied from

Fix bug #SF1541789: Stop spurious syntax errors on unsigned messages.
Problem reported by S. Moonesamy of Eland Systems.
0.4.1 2006/06/14
LIBDK: Properly handle key and policy records that don't have
whitespace after semicolons.
LIBDK: In dk_eom(), return DK_STAT_SYNTAX if dk_skipbody is set.
Failing to do so means a message with a signature header
below which there is no sender header will report a bogus
success status. Problem noted by Lennert Buytenhek.
0.4.0 2006/05/19
Remove spurious CRLFs injected into canonicalization when multiple
body chunks arrive from the MTA. Patch from Suzuki Takahiko
of Internet Initiative Japan, Inc.
If _FFR_REPORTINFO is enabled, don't call dkf_report() if no DomainKeys
context was ever created for a message.
Simplify dk_sterilize() a little, and handle failures from it.
Problem reported by Fredrik Pettai.
RFC2822 doesn't require any recipient headers, so remove those checks
inside _FFR_REQUIRED_HEADERS.
Fix bug #SF1485119: Canonicalize in the correct order when not using
"-H" on the command line. Problem noted by S. Moonesamy of
Eland Systems.
Activate _FFR_MACRO_LIST and _FFR_EXTERNAL_IGNORE_LIST.
LIBDK: New flag DK_OPTS_HDRLIST for dk_options().
0.3.4 2006/05/02
If _FFR_REPORTINFO is enabled, send reports on all failures, not just
those which aren't in test mode.
Ignore unknown tags in keys and policies, rather than returning an
error.
LIBDK: Return an error if the signing function returned success but
also reported a zero-length signature. Reported by
S. Moonesamy of Eland Systems.
LIBAR: Add a timeout to the I/O wait so that retransmissions
actually get done while waiting for activity.
0.3.3 2006/03/13
Fix test mode check at the end of mlfi_eom(), which was overriding
any configuration settings from the command line.
Reported by Arkadi Poliakevitch of Invidi Technologies.
Copy the value of -C before parsing it so the output of "ps" doesn't
get munged. Reported by Arkadi Poliakevitch of Invidi
Technologies.
Fix "-o", which wasn't actually working at all. Reported by Ben
Lentz.
Add _FFR_LOG_SSL_ERRORS which sends to syslog errors reported by
the OpenSSL libraries.
0.3.2 2005/12/12
Patch a small but definite memory leak. Reported by Ray Krebs
of eBay.
0.3.1 2005/12/02
Tolerate "b=" in signature headers at places other than the end
of the signature (and, in fact, other things at the end
of the signature). Reported by Jason Long. (Bug SF1234164)
Don't reject or report about messages which fail verification
when the sending domain advertises that it's in test mode.
Patch from Adrian Havill.
Fixes to POPAUTH compilation from S. Moonesamy of Eland Systems.
Allow "-d" to specify a list from which domains should be read,
and allow wildcarding in domain names. Requested by
Ray Krebs of eBay. (Feature request SF1312453)
Add "-o" command line option to allow certain headers to be omitted
from signing operations. Suggested by Ben Lentz.
(Feature request SF1314350)
LIBAR: Fix a build issue introduced in the last release.
the pkgsrc-wip project. (Take ownership with adrianp's permission.)
=====
The dk-milter package is an open source implementation of the DomainKeys
sender authentication system proposed by Yahoo!, Inc. It consists of a
library that implements the DomainKeys service, and a milter-based filter
application that can plug in to the sendmail MTA to provide that service
to sufficiently recent sendmail MTAs.
An optional asynchronous resolver library is also provided to work around
limitations of the basic BIND resolver which comes installed on most
systems.
