How to do DNS definitions
Authorize your domain
Many ISPs do not accept emails without DNS records called SPF, DKIM and DMARC and your sendings most likely end up in the spam folder. If you want your emails to be sent from your company's sending addresses (from) to Gmail, Hotmail and any other custom domains in a healthy way; You must set DNS records below to the email address you have defined as the sender mail address (from). Get help from your hosting provider to define these records.
Also, you don't need to change your DNS records completely. It is important to add the SPF, DKIM / DomainKey and DMARC records listed below next to the existing records. Please give this information to your hosting company.
After defining the settings, you do not need to contact with us. You can check the verification status of your DNS settings on the
sender accounts page
in your INBOX panel. If you see them "Grey" it has not been verified yet, you can contact the service provider (hosting) from which you receive server service.
In the DKIM record, there should be the domain name you defined as the sender account in the places where your domain.com is written.
DKIM / DomainKey record as TXT
The value for _domainkey.yourdomain.com. ;
The value for genel._domainkey.yourdomain.com. ;
SPF record as TXT
If you already have an SPF record, you can add the following information to your spf line without making any changes to the existing one.
_dmarc record as TXT
v=DMARC1; p=none; sp=none; rua=mailto:email@example.com; ruf=mailto:firstname.lastname@example.org; rf=afrf; pct=100; ri=86400
NOTE: If all records have been entered correctly, the SPF, DKIM, DMARC buttons on the sender account page in your INBOX panel will be green. The example is as follows;
