No, not to everyone on the internet. Just a fully qualified name, which should involve at least a hostname and a top-level domain and a dot in between, with optional parts with domain-names in between. Since "dk." resolves to an A-record, I guess that works as an FQDN. As for how complete myname needs to be depends a lot on what you expect from the machine. Mailservers tend to want to strip the hostname part and default to the domain part of an FQDN if you don't specify otherwise, so for a mailserver, putting "blaha" alone in myname would probably not work out as expected. But for a test-compile-machine in a throw-away VM to see if libblurg can be ported, the name may have zero impact if it isn't well-formed. -- May the most significant bit of your life be positive.
