Hi, Sorry to hear about this problem. I can see that you are using Atlassian Cloud here, and it certainly looks like at least some of these messages are not getting through. It appears that Atlassian Cloud does not yet have a support for the use of this DMARC policy. There is an existing feature request to add support for this in JRACLOUD-40169. I would recommend watching and voting on that issue. This helps our development team to prioritize new features. In the meantime, I also came across a related request in JSDCLOUD-5614. That issue appears to have documented some work-around that might be helpful here: Workaround : Whitelist IP range from this https://confluence.atlassian.com/cloud/atlassian-cloud-ip-ranges-and-domains-744721662.html Use From: address the default @.atlassian.net email address I hope this helps.
