SPF Management

SPF Management is included as part of the DMARC add-on.

SPF records ensure emails are sent from an authorized server by comparing the sender's IP address with the domain's DNS records.

Benefits

Overcome SPF limitations with simplified management.
Configure SPF settings directly in your Harmony Email & Collaboration Administrator Portal.
Seamlessly integrate with the DMARC solution for ongoing monitoring and issue resolution.

High-Level Procedure

Add the authorized sending sources through the Harmony Email & Collaboration Administrator Portal. See Adding New Source to SPF Records.
Activate SPF Management by updating the DNS SPF record with the required include statement. See Activating SPF Management.
Check Point manages authorized sending sources for each domain.
Modify sending sources as needed through the Harmony Email & Collaboration Administrator Portal. See Managing Sending Sources.
Check Point ensures seamless operation beyond SPF limitations.

Reviewing the SPF Status of your Domains

The SPF Management page shows a list of all the organization's protected domains and sub-domains.

To view the SPF Management page, access the Harmony Email & Collaboration Administrator Portal and click DMARC > SPF Management.

Column Description

Domain

Domain name.

SPF Monitoring

Monitoring status of the domain.

Managed - Check Point manages your SPF.

Pending - The Check Point SPF is not yet active. To activate it, update your domain's SPF record in your DNS to include Check Point's SPF entry.

Note - DNS records may take some time to propagate across the internet.

Not Managed - The Check Point does not host your domain's SPF record yet, but the necessary settings are configured and ready for deployment.
Not Available - SPF management is unavailable for onmicrosoft.com sub-domains, as Microsoft controls these DNS settings centrally to ensure consistency and security. For full DNS and email authentication control, use a custom domain.

SPF% Success

The percentage of emails that pass SPF out of the total number of reported emails sent by the domain.

Managed sources

Number of managed sources in the domain.

Last Updated

The date and time of the last update.

Hosted Domain

Name of the hosted domain.

Activating SPF Management

Harmony Email & Collaboration uses the SPF Macro Mechanism, which allows an unlimited number of SPF entries to be defined.

To activate the SPF Management for Harmony Email & Collaboration, edit your organizational domain's DNS SPF record to include this statement:

include:{code}.spf.checkpoint-spf.com

or replace it entirely with this SPF record:

v=spf1 include:{code}.spf.checkpoint-spf.com ~all

where {code} is the unique code specific to your organization. You can find the code from the Instructions widget.

Once the new SPF record is active in your DNS, Harmony Email & Collaboration verifies it and activates SPF Management.

Adding New Source to SPF Records

To manually add a new source to your SPF record:

On the SPF Management page, click the domain to which you need to add a source.
Click Insert Source next to the Instructions at the top of the page.
In the pop-up that appears, select the mechanism from the Mechanism list.
- ip4: Matches specified IPV4 or IPV6 addresses
- ip6: Matches specified IPV4 or IPV6 addresses
- include: Use SPF rules from another domain
- a: Matches domain's A or AAAA records
- mx: Matches domain's MX records
- exists: Matches if a DNS query returns a result
In the Value field, enter the value relevant to the selected Mechanism.

Examples of Value for different Mechanisms:
- ip4:
  - Single IP: 192.0.2.1
  - Subnet: 192.0.2.1/16
- ip6:
  - Single IP: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
  - Subnet: 2001:db8::/32
- include: _spf.example.com
- a: Specify a domain or leave it blank
- mx: Specify a domain or leave it blank
- exists: %{i}._spf.example.com
In the Notes field, enter the description as required.
Click OK.

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.

Configuring the SPF Record

By using these SPF qualifiers in the SPF record, you can define the action for emails sent from unauthorized sources.

Fail (-all): Rejects the email (Recommended).
SoftFail (~all): Flags the email as a SoftFail and may be rejected.

Allow (+all): Allows the email.

Important - Check Point recommends avoiding this qualifier, as it allows any IP address to send emails on behalf of your domain.

None: It defines no specific action.

Note - Ensure that your domain has a default SPF policy.

Defining the SPF Record

You should configure the main SPF record with the appropriate policy in your DNS settings.

Note - Since SPF is managed at the DNS level, you do not need to configure the policy in the Harmony Email & Collaboration Administrator Portal. These settings will not impact the SPF evaluation result.

Managing Sending Sources

You can manage your authorized sending sources as required. To do that, click the icon from the last column of the Sending Sources table.

To insert the source, click Insert Source Above / Below. In the pop-up that appears, select the required options and click OK.

You can also click Insert Source directly next to the Instructions at the top of the page. In the pop-up that appears, select the required options and click OK.
To delete a source, click Delete Source. In the confirmation pop-up that appears, click OK.
To update the source, click Update Source. In the pop-up that appears, make the necessary changes and click OK.

To modify the prefix of the all element in your SPF record, click Update Prefix. In the Update Prefix pop-up that appears, make the necessary changes and click OK.

Note - This option is available only for sources with a preconfigured prefix.

After making the changes, click Save & Update to generate the SPF record based on the configured sources.
