The number the provide to customers is 1-866-291-7726. I'm not sure they will talk to you if you are not a customer but the call is on their dime so it might be worth a shot. -jim James Rupprecht Senior Systems Specialist Microsoft Exchange & Active Directory Administrator University of Kansas Information Technology -----Original Message----- From: Jason Gurtz [mailto:jasongu...@npumail.com] Sent: Monday, May 23, 2011 11:56 AM To: MS-Exchange Admin Issues Subject: Anyone know how to report spammy MS hosting customers? We have been receiving spam from a certain MS customer for several months now, sent to a couple role email addresses that clearly have been scraped from our website or garnered through purchased lists. No way this went through confirmed opt-in... It's not terribly high volume, but it's also not going away. If you try emailing ab...@microsoftonline.com you will find that it doesn't exist (FOR SHAME!) via an NDR from bigfish.com. Reports sent to ab...@bigfish.com seem go to Frontbridge and that seems to be a black hole. Out of desperation I emailed doma...@microsoft.com (the only contact you'll find in whois) and I did receive a human response. That is amazing, but they seem quite unwilling to help or care in this context. So, htf should one go about getting a spammer kicked off MS business hosting? It's irritating enough that a spam-l posting will probably happen soon. Hope someone gets their ass in gear quick-like up in Redmond. ~JasonG --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
