Thanks, so FQDN means that there MUST always be at least one dot in the hostname. What if I use, which is a public domain owned by me, instead of your example olsen.intra? Does that cause any conflict?
To your first question: that a FQDN has at least one dot is a result of
its definition. Chris already gave a link. In addition

If you use a valid, because public resolvable domain name there is always the risk that as effect a service request - here mail routing - goes a different route than you would expect and want to. I mean, if the resolvable domain name has DNS records poiting to different locations. To be specific: Sendmail does MX lookups and a query for your "" domain gives a valid result:
$ host -t mx mail is handled by 10

Sure, you can try to avoid such pitfalls by doing specific setup "tricks". But isn't it easier to simply use a namespace for your LAN where there is no risk it would be resolvable for any public meaning?
