Longer-term, you might also try it this way (correct the newline
in the last phrase, where my MUA would line-wrap):
=================================================================
warn
verify = sender/callout
log_message = Unverified sender at $sender_verify_failure \
for $sender_address
==================================================================
Then, after a few hours or days:
$ grep 'Unverified sender' /var/log/exim/mainlog
- and take note of how many false-positives you may be
experiencing with a 'hard' "require verify = sender"
Few correspondent mx will go all the way, some won't respond at all.
YMMV
