Why is Avanan showing up in my DMARC reports and how do I fix it?
Summary
What email marketers say13Marketer opinions
Email marketer from EmailSecurityFAQ shares that using multiple email security solutions like Avanan alongside existing ones can sometimes cause conflicts. Make sure that Avanan is correctly integrated into your email flow and properly authenticating emails to prevent DMARC issues.
Email marketer from EasyDMARC advises regularly reviewing your DMARC reports to catch any unauthorized sending sources. If you see Avanan or other unexpected sources, investigate and update your SPF/DKIM records accordingly.
Email marketer from emaildelivery.com, a mailspike company recommends continuous monitoring of your DMARC reports, setting up alerts, and actively troubleshooting any failures. This is a proactive approach to managing email authentication and deliverability and allows you to catch third party software quickly.
Email marketer from EmailAuth recommends using DMARC reporting tools to identify the source of DMARC failures. These reports can show you which IP addresses are sending emails on behalf of your domain and whether they are passing SPF and DKIM.
Marketer from Email Geeks suggests checking with finance for PO/invoice details to identify if the client uses Avanan's encrypted mail offering, which might be causing the issue in DMARC reports. It could be a case of shadow IT where someone bought the service without informing IT.
Email marketer from Avanan Community Forums explains that if you are using Avanan for email security, its servers will process your outbound email. This can lead to Avanan's IPs showing up in your DMARC reports as a sending source. It's not necessarily an error, but a reflection of Avanan's role in your email flow.
Email marketer from StackExchange explains that when using a third-party service like Avanan, you must ensure your DKIM signatures are valid and aligned. Work with Avanan to verify they are correctly signing emails on your behalf.
Marketer from Email Geeks suggests that if the client's SPF record includes Checkpoint's IP address, it could be causing SPF to pass even if DKIM is still the client's. This is particularly likely if receivers are using Checkpoint.
Marketer from Email Geeks clarifies that DMARC only requires either SPF OR DKIM to pass. A simplistic dashboard might show 100% pass even if only one mechanism (SPF or DKIM) is passing alignment. The SPF needs to include the IPs in the SPF record for alignment.
Email marketer from Mailhardener suggests that if you suspect Avanan is causing issues, check its email reputation and deliverability. Poor reputation can lead to DMARC failures. Monitor Avanan's sending practices and ensure they align with best practices.
Marketer from Email Geeks suggests a few possibilities: a) receivers using Checkpoint (with the Checkpoint IP in the SPF being a red herring), b) re-routing occurring, or c) something being missed. Because Avanan is listed in the SPF record currently, this is causing SPF to pass.
Email marketer from MXToolbox suggests checking your DMARC record to see if it's set to 'quarantine' or 'reject'. This can help you understand how receivers are handling emails that fail DMARC checks. Use MXToolbox's DMARC lookup tool to validate your record.
Email marketer from Reddit explains that if Avanan is an authorized sender for your domain, you need to ensure it's properly included in your SPF record and/or signing emails with DKIM. If Avanan's IP addresses aren't in your SPF record, or DKIM isn't configured correctly, it will cause DMARC failures.
What the experts say1Expert opinion
Expert from Spam Resource (John Levine) explains that if Avanan is legitimately sending mail on your behalf, its servers and IPs need to be authorized in your SPF record. He suggests verifying that the SPF record includes Avanan's designated mechanisms to ensure SPF passes, and advising to also verify that the DKIM configuration is correct if being used.
What the documentation says4Technical articles
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.
Documentation from DKIM.org explains that DKIM alignment is crucial for DMARC to pass. Ensure that the domain used in the DKIM signature matches the domain in the 'From:' header. Work with Avanan to ensure they are signing emails with a DKIM selector that is properly configured for your domain.
Documentation from SPF Record Syntax explains that your SPF record needs to authorize any third-party senders like Avanan. You can include their IP addresses or domain using 'include:' mechanisms in your SPF record. Make sure the SPF record is correctly published in your DNS settings.
