Most of this means very little to me. Is there somewhere I can go to read about these DNS records?
SPF and DMARC records
are fairly easy to set up.
DKIM is more difficult

because you have to generate a private/public key pair, publish the public one in a DNS TXT record for YYYYMM._domainkey.fullyqualified.domainname.tld and then teach your Mail Service (say postfix) how to sign each message that it sends out with the private key which is secretly stored on your server.
Best wishes, Roland
