- fix compatibility with Berkeley-DB < 4.1

- updated whitelist
- don't be pedantic about wrong reverse-dns entries: it doesn't really help

(CVE-2005-1127)
- fix crash with '%' in sender addresses (Stefan Schmidt)
- fix other users of unchecked strings with syslog/printf (Peter Bieringer)
- run in tainted mode -T (Peter Bieringer)
(version 1.19 and 1.20 were released on the same day with the above fixes)
* 2005-03-07: version 1.18

is put in the headers (Bernhard Weisshuhn)
- syslog delays (when a X-Greylist header is added)
- bugfix: sometimes the retry-window was not properly enforced
- bugfix: argument parsing in postgreyreport (MJH)
- include the recipient-domain in the default --greylist-text so
that the concerned mail-server can be determined and a contact-address

is used (Adrian 'Dagurashibanipal' von Bidder)

it is turned on by default, to disable it specify
--auto-whitelist-clients=0

greylisted (Stephen Gildea)

- fixed --retry-window with hours (Tom Baker)
- update postgreyreport to version 1.14.2 (Tom Baker)
- update whitelist
* 2004-07-12: version 1.14
- lookup-by-subnet is default. "transition code" has been implemented, so that
also a lookup with the unstripped IP will be tried. That way you shouldn't
loose any data from the database when moving to version 1.14. Use
--lookup-by-host for the old behaviour. All "address pool" entries are
removed from the whitelist...
- loosen "IP in reverse name" test (Matt Egan)
- changed default --max-age to 30, since the db should shrink a lot
because of the --retry-window functionality (you might want to
db_dump/db_load your db to make it really shrink on disk)
- another Perl 5.8.0 workaround
- implemented --greylist-text (Tom Baker)
- replaced X-Postgrey header with a X-Greylist header which is more similar
to what greylist-milter does (Stephen Gildea)
- implemented --greylist-action (Stephen Gildea)
- updated postgreyreport (Tom Baker)
- update whitelist
* 2004-07-05: version 1.13

VERP addresses are substituted to a unique string.

- when doing keys maintenance: report about how many keys there where before
and after.

* 2004-06-03: version 1.5

mailers that try again the first time after 8 minutes and it doesn't seem
to matter right now for filtering spam: they never come again)
- report in the log the real time that is left, after which the triplet will
be accepted
- traverse the database for cleaning old entries only during the night
and only once per day
- more efficient traversal of database for cleaning (Matthew Reimer)
- fix syslogging of warnings and fatal errors
* 2004-05-24: version 1.4
- log removal was not working (need to call txn_checkpoint first)
* 2004-05-22: version 1.3
- PID file generation with --pidfile (Ralf Engelschall)
- fix opening of unix socket (Ralf Engelschall)
* 2004-05-21: version 1.2
- create files readable only by the user (umask 077)

and not who did implement it (which is mostly me)
