Personally, I don't buy that in the Microsoft case, for two reasons: (1) it takes a lot of time until a link gets examined by the system or an operator or whoever is issuing the requests (2) they only do HEAD requests, which do not give any in terms of (spam/malware protection) relevant information about the websites contents. Of course, it's possible that Microsoft just didn't do a great job in building that system. regards, Jonas _______________________________________________ cryptography mailing list [email protected] http://lists.randombit.net/mailman/listinfo/cryptography
