In the Value field, enter the value relevant to the selected Mechanism.
Examples of Value for different Mechanisms:

To add a new source to your SPF record from a list of known sources:
On the SPF Management page, click the domain to which you need to add a source.
Click Add Source from List next to the Instructions at the top of the page.
In the Source section, select the required source and click OK.

Note:

If you add a source from a predefined list (for example, Atlassian) or add a domain/subdomain, the system automatically updates the DNS records every few minutes or hours.

For example, if you add an IP address to a subdomain, the system automatically updates it through the SPF management mechanism.
