Basically to prevent spamming, phishing or hacking our emails system we needs some TXT Records in Our DNS like SPF, DMARC, DKIM. DKIM is one of these which refers to DomainKeys Identified Mail. It is a technical standard that helps protect email senders and recipients from spamming, spoofing, and phishing. It is a form of email authentication that allows an organization to claim responsibility for a message in a way that can be validated by the recipient. Here we are adding DKIM Records For Emails to prevent emails bouncing, spamming or phishing.
Adding DKIM Records For Emails
1. Generate DKIM Public Key and Private Key and add the key or DomainKey Selector(this can be any random alphabets or numbers)
2. Add TXT Record in DNS as:

3. Add Private Key at Email Service Provider, generated at step 1
4. After adding you can check TXT DNS here
