01/05/2006 : V 1.7
- Removed the KEEPDBOPEN option as it could lead to multiple instance of gld running
when mail traffic is low and thus father process MYSQL connection timeout .
Furthermore, after tests, efficency is the same .
KEEPDBOPEN option is now silently ignored to forced to NO .
16/09/2005 : V 1.6
- Removed the algorithm lightgreydomain as the new mxgrey does better and simpler
- Removed the UPDATE option, now gld always update triplets .
- Fixed a minor flaw in the MXGREY algorithm.
- Now you can configure MXGREY to consider an ip as a safe MX after X succesful
greylists instead of only 1 . (read gld.conf for details)
- Now gld updates the counters only when mail is not greylisted
- Added Training mode, read gld.conf for details
- Now gld verify that if you supply a custom smtp code, it's a 4XX code
otherwise gld discard it and use 450 .
- If gld cannot connect to MySQL server on startup
it will not refuse to run anymore, but will set keepdbopen to 0 and accept to run .
- The sample config file provided now only listen to loopback
only accept connection from localhost and runs as nobody/ nobody.
WARNING: if you were using lightgreydomain algorithm, it has been discontinued
use MXGREY in place, please read gld.conf for details.
21/04/2005 : V 1.5.2
- Fixed a bug in MXGREY algorithm
13/04/2005 : V 1.5
- Fixed several possible buffer overflow by removing all sprintf() calls
and replacing them by snprintf()
- Added pgsql support, use configure --with-pgsql to compile
gld with pgsql support
- Added the MXGREY parameter, please read gld.conf for details.
- Added KEEPDBOPEN parameter, please read gld.conf for details.
- Added Configurable SMTP return code
- Updated the white list to the lastest known.
19/08/2004 : V 1.4
- Added the USER and GROUP parameters to allow running gld
as a specific user/group instead of root.
- Added the LIGHTGREYDOMAIN parameter for greylisting on domains
please read gld.conf for details.
- Added CLIENTS parameter, to restrict clients allowed to connect to gld.
15/08/2004 : V 1.3.1
- Parameters are now checked to avoid a possible buffer overflow
- Parameters are now checked to avoid a possible SQL injection
- Fixed the bug which makes gld crash when displaying infos for an empty database
19/07/2004 : V 1.3
- Now, when LIGHTGREY is active, full ip+network is checked in whitlists
instead of the network only.
- Added the LOOPBACKONLY parameter, to make gld listen only to loopback (127.0.0.1) .
- Added the DNSW parameter for DNS whitelist support (cf DNSWL in gld.conf)
- Added the FACILITY parameter to define the syslog facility we want to use
- Added the -C switch to simulate what -c would do
- Added the -k and -K switchs to clean the one hits entries in the database
- Added the -i switch to display some database informations
- Added the -d switch to enable debug mode
- Added in the documentation a mini howto to setup postfix to greylist only some emails/domains.
25/06/2004 : V 1.2
- Improved child management to avoid zombies on some BSD.
Thanks to Michael Rasmussen <mir@datanom.net> that solved the bug that caused
gld to leave spawned children as zombies on BSD.
- Added the light greylisting algorithm (cf LIGHTGREY parameter in gld.conf).
- Added the -c option to gld to clean up the database (try gld -h).
- All options have now a default value and are no more mandatory.
- gld now use a configure script and should be easier to compile on some unixes.
- Improved documentation and given a postfix configuration example.
