 To be able to do this yourself, you need to have access to the DNS server for your domain. This might be your own DNS server, or one provided by your domain registry.
-Now you need to generate a public key to put into a TXT record for your domain. To do this, search for a DKIM key generator, like [[http://dkimcore.org]], and enter the domain you want to put DKIM onto. This will generate a public key and a private key, and also a selector.

+Now you need to generate a public key to put into a TXT record for your domain. To do this, search for a DKIM key generator, like [[http://dkimcore.org]], and enter the domain you want to put DKIM onto. This will generate a public key and a private key, and also a selector. The selector generated by dkimcore.org will look something like **<number>.<domain name>**, but you can actually use any selector name you wish.
 On the DNS server, create a new TXT record, with a host name of the <selector>._domainkey.<domain name> - for instance **1532654.example._domainkey.example.com**. Copy the public key from the key generator, and paste it into the TXT record's data. Remember to remove the speech marks and any spaces in the key. Apply the changes on the DNS server.
