Exim's submission mode is set on a per-message basis
under the control of the local configuration.

The example config file in Exim git sets submission
for
a) anything received from a named-list of hosts
    (the "list" can be static, can be a DB lookup).
    The list is called "relay_from hosts" which is
    a hint as to the intended use - but names are only
    interpreted by the config, not meaningful to the
    Exim code.
b) anything received under SMTP authentication
