Do you want one of us to resend the patch > or will you be able to do it? Hi Anchal, Usually this is due to how DMARC is set up for amazon.com. When mail lists relay your messages without taking ownership of the envelope, it invalidates the DKIM signatures and the DMARC policy can cause email to be flagged as forged / spam. If you configure your mailer and git to use amzn.com instead of amazon.com it may help, as the DMARC policy for amzn.com is "none" [1] rather than "quarantine" for amazon.com [2]. --msw [1] https://mxtoolbox.com/SuperTool.aspx?action=dmarc%3aamzn.com&run=toolpage [2] https://mxtoolbox.com/SuperTool.aspx?action=dmarc%3aamazon.com&run=toolpage
