You correctly spotted sender_unqualified_hosts and it is the option to
use in this case. Setting "control = submission" will not make Exim
accept an address without a domain part, you'll have to set
sender_unqualified_hosts. If your client hosts are dynamic, you could
set it to *. If your clients connect to some other port than 25, you
could do this (untested!):
SEnder_unqualified_hosts = ${if =={$received_port}{25}{}{*}}
This will make sender_unqualified_hosts empty for port 25, but * for
everyone else.
