dig, by default, only queries A records. You should also test:

dig AAAA <result-of-above-dig>

Also, all these commands may return several results so you may need a
loop (pseudo-code, untested):

for name in $(dig +short -x $OUTGOING_EMAIL); do
   dig A $name
   dig AAAA $name
   check-results
done
