Hi Mailgun team,

I'd like to request a feature that allows users to customize or override the SPF record value required for domain verification.

In our case, we're running into the 10-DNS-lookup limit imposed by SPF, and the default include:mailgun.org already consumes multiple lookups. To maintain compliance and avoid delivery issues, we want to flatten and self-host the Mailgun SPF entries (e.g., using a subdomain like spf.ourdomain.com) and reference that instead.

Currently, domain verification fails unless the exact include:mailgun.org is present, which prevents this workaround.

Please consider adding the ability to:

Customize the SPF value used for verification

Or provide a static, up-to-date flat IP list for customers to reference

This flexibility would help users with complex email setups or multi-service SPF constraints.

Thanks in advance!

Best regards,
