Keep replying, and explain why you can't enroll in SNDS, and ask them to ... "Escalate". That's all I can suggest, sorry.
Aloha, Michael. -- Michael J Wise Microsoft Corporation| Spam Analysis "Your Spam Specimen Has Been Processed." Open a ticket for Hotmail<http://go.microsoft.com/fwlink/?LinkID=614866> ? From: mailop <mailop-boun...@mailop.org> On Behalf Of Robert Schoneman via mailop Sent: Thursday, April 29, 2021 5:27 PM To: mailop@mailop.org Subject: [EXTERNAL] [mailop] Microsoft Consumer Email Deliverability Issue We're having issues sending order confirmations from our event ticketing system to users of Microsoft's consumer email services (Outlook, Hotmail, Live, MSN). The order confirmations are being sent to Junk. Some details are below this paragraph. I've communicated with Microsoft's "Outlook.com Deliverability Support Team" and while they were very responsive, unfortunately we hit a roadblock. They wanted us to enroll in JMRP and SNDS. Microsoft's JMRP system requires enrollment in SNDS. However, to enroll in SNDS requires verifying ownership of the sending IP's. We don't own them. Our event ticketing system vendor who does hasn't been helpful. We own the sending domain. * SPF, DKIM, DMARC are all good and show as "pass" in the email headers of messages sent to junk. * Sending IP's have the correct PTR records. * Looking at the headers of a message sent to Junk, I see that our PCL = 2, SCL = 0 and BCL = 0. * MS confirmed our sending IP's and domain aren't the issue: "We were unable to identify anything on our side that would prevent your mail from reaching Outlook.com customers." * MS did however determine that "messages are being filtered (i.e. sent to the Junk folder) based on the recommendations of the SmartScreen Filter." * Email messages from the same sending domain and IP's, using the same address, which are other than order confirmations (reports, for example) deliver to my Outlook.com email address' Inbox without issue. * The offending emails have * No attachments * One image stored on the same domain the message is sent from * No links * No card info * A name and email address matching the recipient * All emails are sent from a valid address and all NDRs/bounces are resolved. * No marketing or bulk mail is sent from the domain. * The same emails sent to Google, AOL, Yahoo deliver without issue. I'm out of ideas here and would welcome any help on or off list. Our concern is if we can't deliver an order confirmation to our customers who use these email services, we'll also have issues delivering their electronic tickets.
