DomainKeys Identified Mail (DKIM) lets an organization take responsibility for a message that is in transit. DKIM attaches a new domain name identifier to a message and uses cryptographic techniques to validate authorization for its presence. The identifier is independent of any other identifier in the message, such in the author's From: field.
It is highly recommend to use DKIM to ensure proper email delivery to domains such as gmail.com and outlook.com. Mail servers increasingly are using SPF and DKIM to validate messages and send messages that don't include DKIM and SPF to SPAM or Junk folders.
Setting up a DKIM record is different for all DNS servers. To makes things easy, here are the instructions for GoDaddy, Namecheap, 1&1, Network Solutions, and Google Domains.
Your services might be very different and we highly suggest you contact your systems administrator to get your DKIM implemented.
"supportbench-dkim1._domainkey" pointing to "supportbench-dkim1._domainkey.supportbench.net"
"supportbench-dkim2._domainkey" pointing to "supportbench-dkim2._domainkey.supportbench.net"
Once the DKIM cname record is setup, you will need to enable DKIM signing on the email addresses you want to use.
Your DKIM is all setup.
