Lots of applications want this > (ie. sendmail). Then sendmail is broken (or misconfigured). But you are only partly right, sendmail uses hostname as the name of the sending computer and will add the domainname if you leave it out of hostname. Sendmail will work even if the hostname is totaly wrong, but your e-mails may be rejected från the other end. I have a lot of systems that do not have a FQDN, but a resolvable name, that is a name that exists in the DNS domain they are part of. I have not found a program that breaks because of that. But I have a trick question for you. What shoud I set as hostname if I have a mobile computer that will have diffrent IP-adresses at diffrent times during a session? And those are in diffrent DNS domains? And it is not connected to the network when I turn it on?
