The notion of a single-component FQDN would be quite a breakage for the basic concept of using both FQDNs and Unqualified names.
Well, you know, there's a guy whose email address has been n@ai for many years. People have varying amounts of success sending him mail.
My Zimbra UI says it "might be invalid"; the default postfix config inside it tries to send it to n@ai.baylink.com, and complains because the domain won't resolve. If I'm reading 3.2.4 of 2822 properly (that notation is one I'm not entirely familiar with, and should be), that really is a valid 2822 address, as odd as it sounds. Clearly, it's semantics are unexpected, though. I guess I should go hang a bug on it. Cheers, -- jra -- Jay R.
