If the Sender field contains the FQDN of the host, and the machine is
turned off, you're screwed.  So maybe it is better to give a domain
part in the address which identifies a host which is sure to be on?
Maybe this is the case in my situation?  How can you know?  How can
Gnus know?

Why do you want to forbid me from putting there an address which I
know to work better than user@FQDN?

Reall?  What is the FQDN needed for?  The address should specify a
mailbox, and knowing about host names is not necessary for specifying
mailboxes.
