Summary

Avanan's presence in DMARC reports is often due to it processing outbound emails as a security solution. The issue typically arises when Avanan isn't properly integrated into your email flow or isn't correctly authenticating emails. Correct integration includes verifying that Avanan is authorized in your SPF record (including their IPs), and signing emails with DKIM and ensuring proper DMARC alignment (SPF or DKIM needs to pass with alignment of the 'From' header). Conflicts can occur when using Avanan alongside existing email security solutions if not properly set up. It's recommended to regularly review DMARC reports, use DMARC reporting tools to monitor sending sources, and check Avanan's email reputation and deliverability. Also confirm with the finance department if Avanan has been purchased or is being used on a trial basis, as it may be 'shadow IT'.

Key findings

  • Avanan as Sender: Avanan shows up because it's processing your outbound email.
  • SPF & DKIM Alignment: Proper SPF and DKIM configuration are essential for DMARC to pass. Ensure 'From' header alignment.
  • Authorization: Avanan's servers/IPs must be authorized in your SPF record.
  • Conflict with other solutions: Using Avanan with other security solutions can cause conflicts if not configured correctly.
  • Reporting & Monitoring: Regularly reviewing DMARC reports is crucial for identifying issues.
  • Finance Department: Confirm with the finance department that there is a business account with Avanan.

Key considerations

  • SPF Record: Verify that Avanan's IP addresses or domain is included in your SPF record.
  • DKIM Setup: Ensure Avanan signs emails with a valid and aligned DKIM signature.
  • DMARC Reports: Use DMARC reporting tools to identify the source of DMARC failures.
  • Email Reputation: Check Avanan's email reputation if deliverability issues are suspected.
  • Solution Integration: Make sure Avanan is properly integrated into your email flow.
  • DNS Publishing: Ensure that the SPF record is correctly published in your DNS settings.

What the documentation says

4 technical articles

DMARC failures occur when the 'From' domain doesn't align with the authenticating domain (SPF or DKIM). For Avanan, ensure it's authorized in your SPF record using 'include:' mechanisms and that DKIM signatures align with the 'From' header. Improper forwarding or modification of the 'From' header without correct SPF/DKIM configuration can lead to DMARC failures. Proper DNS publication of SPF records is critical.

Key findings

  • DMARC Alignment: DMARC requires alignment between the 'From' domain and the domain used for authentication (SPF/DKIM).
  • SPF Authorization: Third-party senders like Avanan need to be explicitly authorized in your SPF record.
  • DKIM Alignment: DKIM signatures must align with the domain in the 'From' header for DMARC to pass.
  • Forwarding Issues: Improper email forwarding or 'From' header modifications can cause DMARC failures.

Key considerations

  • SPF Configuration: Include Avanan's IP addresses or domain using 'include:' mechanisms in your SPF record.
  • DKIM Verification: Ensure that DKIM signatures are valid and properly configured for your domain.
  • Header Integrity: Avoid modifying the 'From' header during email forwarding without proper authentication.
  • DNS Publication: Ensure that the SPF record is correctly published in your DNS settings.

Technical article

Documentation from Microsoft explains that DMARC failures occur when the 'from' domain in an email doesn't align with the domain used to authenticate the email (SPF or DKIM). If Avanan is forwarding emails it may be altering the 'from' address or other headers leading to DMARC failures, and should be configured correctly.

Technical article

Documentation from DMARC Analyzer explains that DMARC alignment requires either SPF or DKIM to pass, and for the domain in the 'From:' header to match the domain used for authentication. If Avanan is forwarding emails and modifying the 'From:' header without proper SPF/DKIM configuration, DMARC will fail.
