Would you please identify yourself??! I have rather bad feelings about having to follow a discussion where one part is a ghost named "hostmaster". The NL Naming Authority is not a ghost, but a *function*. And it doesn't really matter who in a particular case is speaking on behalf of the NL Naming Authority: the official e-mail address hostmaster@cwi.nl is linked to the function and is always used in the From: field when the message is an official message/reply/statement by the NL Naming Authority. Like in this case. Besides, the standards require that when the From: line differs from the e-mail address of the person who sent the mail, a Sender: line be present. And that's the case in all mails with hostmaster@cwi.nl in the From: line. That's what we call "implicit identification". -hostmaster
