OK, the individual corporate "culture" can certainly be an issue.  I 
guess we still treat email as a convenience with no guarantee of 
delivery.  For our business, if anyone needs immediate, guaranteed 
communication, they still view the phone as the best method 
although various flavors of "Instant Messenger" are often used too.

Hmmm, odd that one, once set up the greylisting hasn't required any 
maintenance over and above review of logs.

Hmmmm, really odd that one!  What were the users doing, in the 
opinion of the researchers, that would cause them to become the 
victims of spam as related to greylisting, or, well, related to 
most any other spam reduction method, I guess.  We've never had to 
go out of our way to encourage spammers to send us mail.

If that were true to any extent I'm sure we would have seen a 
meaningful up-tick in or spam messages but, so far, we've not seen 
it here. 

Interesting, thanks for the notes!
