You're sending "unqualified" addresses. You need to look into the
"qualify_domain" setting.

Those probably only affect inbound mail (assuming that there's a
redirect router referencing that file).

's' is for the "Sender:" header; I note that you don't have F combined
with "hobbit@" there. Setting qualify_domain would put something after
the @ too. "exim -brw" is your assistant here.

Another approach is errors_to on the Router which handles the recipient.
