Mailkit does support DKIM authentication for your outbound emails, along with SPF and DMARC, and recommends that you enable it to protect your domain. To do so you need to contact the Mailkit support team by emailing them at email@example.com.
How to proceed with DKIM public keys?
fter you get your public key from Mailkit’s support team:
- Login to your DNS provider’s management console as the admin
- Navigate to the DNS records section for your individual domains
- Create a TXT or CNAME record depending on the type of DKIM record provided to you
- Copy and paste the hostname and value
- Save changes to your record and wait for 48-72 hours for your DNS to process these changes
