I'm very, very sorry to beat a dead horse, but I'm deeply confused by

STOP USING ANY PUBLIC DNS RESOLVERS WITH ANY MAIL SERVERS!
For the record, my nameserver setting in /etc/resolv.conf was some local
IP address which presumably used an Amazon Web Service (AWS) DNS server.
After changing the IP address to 127.0.0.1 in that file, it changed
itself back to the original IP address after some short period of time.
To fix this, follow the appropriate instructions here:
