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'.

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.
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.

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.
