There is nothing you can do as a "list owner". You will have to talk to your
server's admin. "He/She/They" *have* to implement *at least* SPF and DKIM.
ALL legit outbound mail servers *have* to implement *at least* SPF and DKIM.
If your server's admin can't / won't do this, your only other option is to
move your list to a different server.
