There are multiple reports on Reddit and other places of people getting the explicit "authentication required" SMTP response at much lower volumes. I've also experienced it directly myself, on domains that I directly control that don't do 50 a day, let alone 5000.

[mailop] Outlook Support boilerplate deliverability guidance is outdated
This is a note to whoever maintains the Outlook Support autoresponder email reply templates. tl;dr Almost every single recommended link in the "helpful tips" guidance you're sending is broken - likely because the latest year included in the document is *2007*. (If someone knows of an up-to-date version, I'd be grateful to see it.) Details: When filing an email deliverability problem report with Microsoft, the template text accompanying a "not qualified for mitigation" verdict as received yesterday from outlooksuppor...@microsoftsupport.com, includes this text: "Please note: This outcome indicates behavior that misses standards; please review Improving E-mail Deliverability into Windows Live white paper for helpful tips." The "Improving E-mail Deliverability into Windows Live" link in that text is to this document, titled "Summary of Deliverability Best Practices": http://download.microsoft.com/download/e/3/3/e3397e7c-17a6-497d-9693-78f80be272fb/enhance_deliver.pdf In this document, on page 6, there is a set of five steps, with links to guidance for each one. However, every single one of these links is broken. In Step 1, these links: http://postmaster.live.com/Guidelines.aspx http://postmaster.live.com/Troubleshooting.aspx ... both redirect to this nonexistent page: https://sendersupport.olc.protection.outlook.com/pm/Guidelines.aspx In Step 2, this link: http://www.microsoft.com/postmaster ... redirects to this page, which produces a 502 Bad Gateway error at this writing: https://www.microsoft.com/mscorp/safety/technologies/postmaster/default.mspx In Step 3, this link: http://www.microsoft.com/safety .. redirects to this generic landing page: https://support.microsoft.com/en-us/security ... and this link: https://www.microsoft.com/mscorp/safety/technologies/senderid/default.mspx ... produces a "we are currently experiencing high demand" error. In Step 4, this link: http://support.msn.com/default.aspx?productkey=edfsjmrpp=en-us ... redirects to this page, which is a generic MSN Help page: https://support.microsoft.com/en-us/topic/msn-explorer-help-d1dae677-66d2-b5cf-974d-6d820690 In Step 5, this link: http://support.msn.com/default.aspx?productkey=edfsjmrpp=en-us ... redirects to this page, which is also a generic MSN Help page: https://support.microsoft.com/en-us/topic/msn-explorer-help-d1dae677-66d2-b5cf-974d-6d820690 -- Royce ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
