DKIM Generator

DomainKeys Identified Mail (DKIM)

DKIM or DomainKeys Identified Mail (DKIM) is a protocol that uses encryption to verify the sender of an email address.

This protocol helps your recipients know that the email is really coming from your servers, or servers you authorized to send on your behalf, and not from people pretending to be you.

To begin using our DKIM Generator, first enter the domain you wish to protect.

Then enter the DKIM Selector (arbitrary string used to locate the private key and the public key), and finally choose the Key Size (encryption level).

Hit SUBMIT and you'll be presented with newly generated public and private keys. Below those are your Selector Record and Policy Record. These need to be added to your email sending software and DNS, respectively.

Below you will find 2 records that need to be added to your DNS. This is accomplished by adding the record to your DNS Zone Files or through a tool provided by your hosting company.

The private Key as seen above should be added to your email software, there should be a spot to add it. If there isn't, contact that maker of your email software asking them if they support DKIM."
