That is odd.  It is routine for me to install workstations without "real" 
FQDNs.  My desktop for one has an FQDN as tiikeri.localnet, only because I 
prefer localnet over localdomain.  Postfix works like a champ.  You just need 
to configure postfix.  There is nothing magic about "real" FQDNS as far as 
mail delivery is concerned.  Specifically check in main.cf:  myhostname, 
myorigin.  I think by default:

myorgin = /etc/mailname.
