CHANGES
-------

The major number changes for such things as code rewrites, changes in
syntax, and/or dramatic changes in functionality. The minor number
changes for corrections, enhancements, etc. made to the code. There
is no set schedule for releases.

--TODO--

   +	Suggested by Grant Taylor: mail to a specified admin account
   	using plus-detail address, like admin+user@admin.domain or
   	admin+user_domain@admin.domain.

--0.12--

   !	Fixed some compiler warnings with gcc 4.
   
   !	Address problem with the two pass send and remove report
	strategy. Christian 'CBE' Benner reports that some or all the
	reports are not being removed. Suspect that the mechanism of
	marking the value as an empty string is relying on the BDB
	cache of the record in memory when there only a small number
	of records. When there are a large number of records, then
	record updates are lost. Changed update strategy to be a
	single pass.
   
--0.11--

   +	Requires LibSnert 1.63

   !	Corrected documentation error concerning two cache-type
	options when it should have been cache-file and cache-type.
	
--0.10--

   !	mailReport(): use smtpGetError() due to recent change in smtp
   	API to use error code instead of error strings in libsnert.

  !!	License 1.4 which provides additional details with regards to
  	possible license controls used, the possibility of "phone
  	home code" and its general contents, and related privacy
  	statement.

   +	Add check for filterOpen() got NULL socket address pointer
	passed to filterOpen() which inidicates an unsupported address
	type. The connection is simply accepted to bypass the milter.

--0.9--

   +	From http://www.milter.org/milter_api/xxfi_abort.html

	* xxfi_abort is only called if the message is aborted outside
	the filter's control and the filter has not completed its
	message-oriented processing. For example, if a filter has
	already returned SMFIS_ACCEPT, SMFIS_REJECT, or SMFIS_DISCARD
	from a message-oriented routine, xxfi_abort will not be called
	even if the message is later aborted outside its control.

	Added a stub filterEndMessage() handler in order to signal to
	sendmail/libmilter that it needs to call xxfi_abort when some
	other milters rejects a message during the end of message
	processing. This requires that milter-report be the LAST in
	the milter execution sequence. This allows recording of
	message failures in milters like milter-link, milter-spamc, or
	milter-clamc. Reported by Grant Taylor.

   !	filterClose(): remove reporting of "null workspace error",
	which can occur when a client connection is rejected before or
	by filterOpen().

   !	Minor corrections for gcc -Wall warnings.

  !!	Complete replacement of option specification and no backwards.
	compatibility. The newer format allows for better integration
	of previously undocumented libsnert options and for the
	inclusion of future enhancements.

   !	Replaced smtpSendMail() function with new smtp API, that
	removes any limitations on the size of reports.

--0.8--

   +	Added #define _POSIX_PTHREAD_SEMANTICS to solve Solaris'
   	differences in ctime_r() related to different iterations
   	of POSIX.1 drafts vs final cut.

   !	Fixed report buffer overflow, where not enough space was left
	for the mail headers and lead-in message. Reported by Grant
	Taylor.

   !	Reverted back to libmilter's default (7210s) timeout. This
	should silence many of the reported sendmail to milter timeout
	errors and/or broken connections caused by the milter timing
	out sooner than sendmail does with the current SMTP client.
	The sendmail defaults for each SMTP command and receiving the
	message content is 1h each and so libmilter allows for 2h 10s.
	But in theory you could be DoS for between 5 and 104 hours per
	connection. If you want to change this then set in
	sendmail.mc:

		define(`confTO_DATABLOCK',      `30m')
		define(`confTO_COMMAND',        `5m')


--0.7--

   +	Requires LibSnert 1.57

   !	sendReportNow(): if sending the report to the recipients fails
   	for anything other than a recipient error, continue to send a
   	report to the postmaster.


--0.6--

   +	Requires LibSnert 1.56

   !	Changed install.sh.in to create /var/run/milter/ directory
   	owned by milter:milter and change the default PID_FILE and
   	SOCKET_FILE paths. This provides better privelage/security
   	separation since the milters run as milter:milter.

--0.5--

   !	Check if virtusertable is NOT used to avoid NULL pointer
   	reference.

--0.4--

   +	Requires LibSnert 1.52.

   +	The virtusertable.db is consulted, if in use, to determine if
	there is a catch-all for a domain, ie. @example.com or an
	error: entry so as to avoid many different reports being sent
	to the same user, because of a dictionary attack. Suggested by
	Derek Balling.

   !	Changed -p option to take a word argument as to what level of
	reporting <postmaster> should receive (none, unknown, copy,
	redirect). Suggested by Derek Balling.

   !	Modified the report Subject: line to contain the recipient's
   	address so that <postmaster> can identify different reports.

   !	Fold recipient address used for cache lookupt to lower case.
   	This avoids two or more reports to addresses with mixed case.

--0.3--

   !	Fixed bug when -a specifies only one daily time. Reported by
   	Victor A. Prylipko.

   !	Fixed bug concerning drift in report scheduling. Essentially
	the sending of the reports can take a few seconds to a minute
	or more depending on number of entries, so the current time
	has to be reread before perfoming the sleep calculation for
	the next report.

--0.2--

   +	Requires LibSnert 1.49.

   !	LibSnert smtp.c API changes introduced in LibSnert 1.48.

--0.1--

   +	Requires LibSnert 1.46.
