No, it's sufficient if it's a fully-qualified domain name. You don't
need to have a DNS entry for the FQDN, but it's better if there's
an MX record (for mail delivery). An A record (`pingable address')
is certainly not required. Of course, the FQDN must be from a name
space under your control, otherwise you can't guarantee the uniqness
of the message IDs (which is required for news articles).
