relay_from_hosts is a named list of hosts, commonly host addresses, but
with some internal "magic" if it contains host names.
The above log lines read as if the term "relay_from_hosts" is considered
to be part of a host list, and Exim can't resolve the hostname
"relay_from_hosts".
Are you sure that there is no other place in your configuration, using
the term "relay_from_hosts"? (w/o the plus sign)
Wrong use (Exim would consider relay_from_hosts being a host name)
hosts = relay_from_hosts
Correct use (Exim understands relay_from_hosts as a previously defined
list of hosts (addresses, names):
hosts = +relay_from_hosts
Try using
exim -bP config | grep relay_from_hosts
To be honest, the config snipped you attached to your previous mail
doesn't seem to contain "invalid" use of relay_from_hosts, or, at least
I wasn't able to spot it.
