Disclaimer

SPF Guru is a free, community-supported tool that lets domain owners stay within the SPF ten-DNS-lookup limit using two macro-based hostname includes.

Best-effort service

SPF Guru is offered on a best-effort basis. While we aim for reliable uptime, accurate SPF resolution and secure operation, we do not guarantee the availability, accuracy or continuity of the service. It is not intended to be a mission-critical solution and should not be your only route to DMARC compliance on production mail systems. We strongly recommend configuring DKIM alongside SPF, so DMARC has a second way to pass.

No warranty

SPF Guru is provided “as is” without warranty of any kind, express, implied or statutory, including but not limited to warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the service will be error-free, secure or uninterrupted.

Limitation of liability

Under no circumstances shall the creators, contributors or operators of SPF Guru be held liable for any direct, indirect, incidental, consequential or special damages, including but not limited to loss of data, loss of business, delivery issues, reputational harm or legal disputes, arising from the use or inability to use the service, even if advised of the possibility of such damages.

Your responsibility

By using SPF Guru you accept that it is your responsibility to validate the service in your own environment, monitor your SPF results, and ensure compliance with your organisation's security and email delivery policies. You agree not to use SPF Guru for abusive, malicious or unlawful purposes.

Support

Support is offered on a best-effort, volunteer basis. Raise an issue at github.com/smck83/spf.guru/issues or email helpme@spf.guru. We read everything, but cannot guarantee a response time.

Use of this service implies acceptance of this disclaimer.
