Perhaps that's because linkedin.com does not publish an SPF record.
Linkedin.com publishes an SPF record, but the list change the envelope from, so while they may be an SPF pass it won’t be aligned. If I send this email in plain text, DKIM survives, therefore DMARC pass. If I send this email with plain text and html, the list strips the HTML and DKIM fails. Therefore DMARC fails DMARC=(SPF OR DKIM pass) with domain alignment.
