The portal Mail window will open.
Switch to the Settings section on the left-side menu, select the Mail Server option and click the Add your own domain button.
Enter the company domain name in the field and click the Next button.
The next step is used to prove your domain ownership.
To do that you need to add TXT-record in the control panel of your own domain.
Open the control panel of your domain in another browser tab, copy the bold text provided in the Add domain Wizard and paste it into the appropriate fields in your domain DNS settings.
The Next button will be locked until the TXT entry appears in the DNS settings. Once the DNS settings are updated, the next step of the Add domain wizard will be available.
As soon as the TXT record is created press the Next button of the Add domain wizard.
The same way you need to add MX-record, SPF-record and DKIM-record in the DNS settings.
Just copy the needed information provided in the wizard and pase it into the appropriate fields of the control panel of your domain and click the Next button of the wizard.
When all records are added press the Complete button.
To verify your domain settings, click the button situated next to the domain name and select the DNS Settings option from the menu. The domain settings window will open where the records are checked.
If you see the DNS settings link appearing in red next to the domain name it means that one or several DNS records for your domain are incorrect or not updated yet. Go to your domain settings panel to verify the records. If all is correct please wait till the records are updated as some servers can take up to 24 hours to update DNS information. Use the Verify button in order to update the information.
