[Greylist-users] Is it Possible to NOT use client_ip?

  Using my own greylist implementation [1], I ran two tests over 565,012
tuples [2].  The first one used the full [IP,sender,recipient] tuple using a
1s embargo timeout (otherwise, using realistic values and timings such a
test would take a few days):

	Start: Thu Nov 29 17:08:21 2007 
	End: Thu Nov 29 17:10:59 2007 
	Running time: 2m 38s
	
	Requests:                   565012
	
	...
	
	Tuples:                     499846
	Graylisted:                 499846
	Graylisted-Expired:              0
	Whitelisted:                  6945
	Whitelisted-Expired:             0

  Rerunning to ignore the IP address, but otherwise unchanged from the
previous run:

	Start: Thu Nov 29 17:16:21 2007 
	End: Thu Nov 29 17:19:23 2007 
	Running time: 3m 2s
	
	Requests:                   565012
	
	...
	
	Tuples:                     499846
	Graylisted:                 499846
	Graylisted-Expired:              0
	Whitelisted:                  6957
	Whitelisted-Expired:             0

  A few more, so it appears that you might be able to skip the IP address.
