This section covers several ways to improve authentication process. The available selections are:
- Add hosts that send mail from the current domain. Additional host will be agreed automatically to send email to domain. Host can be added and deleted by using appropriate button.
- Add MX servers to the current domain under the appropriate heading. All MX entry which already set will be permitted to send email to the current domain.
- Add IP address that will be approved for sending mail. Main IP server will be added automatically to the list. Every additional IP should be added in CIDR format. (Example: 192.168.0.1/32).
- Include list allows additional host which have to be set and included in SPF setup. It is beneficial when sending email with other services.
- All Entry, when it’s not included in domain while checked, and not enlisted above.
- Overwriting Existing Entries will pile up existing SPF entry when checked.
