Re: Bogus nic.fr behavior

The two problems I'd particularly like to avoid are the valid looking e-mail address that simply forwards to what appears to be a black hole (some ISPs collecting huge collections of mail no-one ever reads, or at least, never responds to). And worse, the very valid looking "user.registered.dom.ain" where "registered.dom.ain" has an MX record that points to the ISP's e-mail server, and everything looks well configured. Until you try and send mail to user@registered.dom.ain and get back a bounce message "Relaying for that host denied"... kre
