DNSMASQ_WARN reducing DNS packet size

Objective: Get rid of the warnings in the Admin Web Interface "reducing DNS packet size for nameserver OpenDNS Resolver to 1280"

STEP 1:
You can get rid of the warning by adding a config file like /etc/dnsmasq.d/99-edns.conf and using an editor like nano or vi, add the following line below:
edns-packet-max=1280
STEP 2:
Then run pihole restartdns and your Pi-hole will not even try with larger packet sizes (our default is 4096).
pihole restartdns
More Information on the DNS Server accepted Maximum Packet sizes below:

Because this doesn't seem to be documented anywhere properly, I probed all the DNS servers currently offered by Pi-hole to find out their maximum DNS packet size:
