  Sender field must include a mail reachable real address. It is used
when mailbox of From field is not senders real address or it contains
multiple mailboxes.

  Even if user@hostname combination least likely to be
customized/faked, system-name is similar. You can set to variable
`system-name'.

  I think system-name and mail-host-address is different concept. In
some environment, (system-name) does not return reachable address, in
particular a machine is in closed network (in fire wall), dial up
environment or non-internet protocols.

  (system-name) and system-name returns machine address,
mail-host-address returns domain of mail address. In major case, they
may be same or (system-name) and system-name may be a mail
reachable. But I think we distinguish them. And Sender field must be
real mail address.
