Update to 1.6:

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.
