I believe there is a misconception here by the OP (not
by Marc the last poster:
One can have Exim with NO AUTHENTICATION but with relaying
denied to all (or to all except "relay_to_domains" or
from relay_from_hosts).
No authentication methods means that NO ONE can authenticate,
it is separate from "unauthenticated users can relay."
I am new to exim -- so maybe there are holes in my understanding
but here is my relevant piece of config (empty relay_to_domains
and relay_from_hosts lists) -- it is very similar to the defaults
since I started from those:
######################################################
# it's for one of our domains AND one of our users
accept domains = +local_domains
endpass
verify = recipient
# we relay TO these domains -- but this list is currently EMPTY
accept domains = +relay_to_domains
endpass
verify = recipient
# relay for these HOSTS -- but this list is now purely LOCAL hosts
accept hosts = +relay_from_hosts
# Accept if the message arrived over an authenticated connection ***
accept authenticated = *
# if not authenticated and not in the "relay" lists, DENY "relay not
permitted
deny message = relay not permitted
##########################################################
If you authenticate successfully you may relay, but otherwise
you may merely send to "out domains/users". This worked fine
for several days WITHOUT authentication until I could set that
up.
