	My suggestion is that each of us maintains a file of whitelist 
domains (I'm defining those as "domains that should never be blacklisted", 
such as generic ISPs, free web site providers, etc; see my document from a 
week or so back).  Those whitelists will all be checked as part of Paul's 
new project.

	Caching services (akamai) and redirectors (msn, yahoo) go in the 
same category for me; they get whitelisted because they can be used by 
spam and legitimate mail.  I juts removed the last vestiges of yahoo's 
redirectors from the sa-blacklist this morning; I figure that the surbl 
parsing code needs to handle those; if those packages do their job right, 


	should show up as a query for bigspammer.com to the surbl lists.
	I'm maintaining a file of redirector examples and have sent off 
previous versions of that file to Justin and Erik.

	I already have exactis.com and akamai.com/akamaitech.net on my 
	As I stated in the reviewer guidelines document, 
bigevel/sa-blacklist/*.surbl.org are _not_ responsible for catching 
_every_ spam.  If a message has no URL's at all (nigeria/diploma), or has 
only urls that end up at geocities/angelfire/akamai/exactis, we can't do 
anything about those.  Some other piece of the spam recognition puzzle 
will get them.
