Questions
Frequently asked
What is a DKIM selector?
A label that lets a domain have multiple DKIM keys. Your email provider assigns one (like google or s1); it forms part of the DNS record name.
Where does the DKIM record go?
As a TXT record at selector._domainkey.yourdomain.com — replacing 'selector' with the one your provider gave you.
