Live.com’s Spam Filters Out of Control!

It has become apparent that Microsoft has completely lost control over its servers.

I’ve been getting more than a few eMails bounced back recently, of the form:

Recipient: [SMTP: [eMail address redacted]]
Reason: 550 SC-001 (SNT004-MC2F3) Unfortunately, messages from 184.172.98.210 weren’t sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.

This appears to affect eMails directed to @live.com and @Hotmail.com. There may be more, but I haven’t seen any bounce-backs from other domains yet.

I don’t know quite what to make of this. I have contacted my Server Wizard and hope that the situation will be resolved shortly.

In the interim, however, I cannot respond to eMails originating from these domains. All my eMail from each of my domains (including automatically generated eMail from PrefBlog and PrefLetter) is routed through the server at 184.172.98.210.

I apologize for the inconvenience and hope to have this situation resolved promptly.

    If it was a single email that bounced then it could be MS just considered it too spammy, but if all your mail is coming back then 9/10 you’ve been blacklisted. If that’s the case, all the mainstream MS domains will likely be affected… hotmail.com, live.com, outlook.com, msn.com.

    Hope you get it sorted out

    So far I’ve learned about the Sender Policy Framework and Sender Scores. I’ve also found a recent blog post published by the helpful people who want to sell me stuff.

    Oh, what fun!

    I am advised that:

    Conditionally mitigated
    184.172.98.210
    Our investigation has determined that the above IP(s) qualify for conditional mitigation. These IP(s) have been unblocked, but may be subject to low daily email limits until they have established a good reputation.

    Please note that mitigating this issue does not guarantee that your email will be delivered to a user’s inbox.

    Ongoing complaints from users will result in removal of the mitigation.

    Mitigation may take 24 – 48 hours to replicate completely throughout our system.

    If you feel your issue is not yet resolved, please reply to this email and one of our support team members will contact you for further investigation.

    Regardless of the deliverability status, Outlook.com recommends that all senders join two free programs that provide visibility into the Outlook.com traffic on your sending IP(s), the sending IP reputation with Outlook.com and the Outlook.com user complaint rates.

    Junk Email Reporting program (JMRP) When an Outlook.com user marks an email as “junk”, senders enrolled in this program get a copy of the mail forwarded to the email address of their choice. It allows senders to see which mails are being marked as junk and to identify mail traffic you did not intend to send. To join, please visit http://support.msn.com/eform.aspx?productKey=edfsjmrpp&page=support_home_options_form_byemail&ct=eformts.

    Smart Network Data Services program (SNDS). This program allows you to monitor the ‘health’ and reputation of your registered IPs by providing data about traffic such as mail volume and complaint rates seen originating from your IPs. To register, please visit http://postmaster.live.com/snds/.

    There is no silver bullet to maintaining or improving good IP reputation, but these programs help you proactively manage your email eco-system to help better ensure deliverability to Outlook.com users.
