Hi there,
I'm hoping someone from MS can assist me on this as I am having great difficulty getting a resolution. I am the IT admin for an accounting firm, we run Exchange 2003 on premise here and for years have had no mail flow issues. We arent on any blacklists
etc Our IP is 83.70.156.37
A few weeks ago outlook.com/hotmail.com/live.com email accounts started bouncing mail from our exchange server. It turns out one user had tried to send a mass mail about the recent budget in Ireland to approx 500 recipients, our clients, some of whom have
hotmail, live and outlook.com email addresses. I know she shouldn't have done this and sue our third party mailchimp subscription instead, it was however a once off. I thought after a week or two the restriction would be lifted but not so.
Microsoft flagged this I have discovered as name space mining. 3 weeks have passed now and we are still unable to send email to our clients using hotmail addresses. this is now a serious issue for our business and for our clients. The income tax deadline
in Ireland is looming and email correspondence to clients is crucial. Clients are annoyed also as they don't understand why hotmail wont allow them receive mail from their accountants.
how can I get this block lifted? We arent spamming anyone, our mail server is fully patched and secure,, running Symantec Mail Security for Microsoft Exchange. No other ISP or mail recipient is blocking any mail from us except MS. On dnsstuff.com we arent
listed on any blacklists.
I have completed this support form multiple times now but I just get the same response every time telling me we are blocked for namespace mining.
It seems we are banished indefinitely by MS and its a big issue for our business now as it is dragging on and on. Ok, a user sent one mail she shouldnt have to a large group of recipients, but it seems we are being punished an inordinate amount for this.
I need to find a way to get this block lifted urgently please.
Help much appreciated!
Thank you
