Dear support,
One of our domain accounts was hacked and used to send out spam.
This issue has been resolved days ago.
We still get the following message when we try to send mail:
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<baanmeubelen.nl #5.7.1 smtp;550 5.7.1 Service unavailable; Client host [82.161.66.211] blocked using Blocklist 1; To request removal from this list please forward this message to delist@messaging.microsoft.com>
We followed the instructions more than a few times and got a response aswell (with case number).
But it's been for days now and we're still being blocked.
Is there anything we can do to get our IP 82.161.66.211 delisted from the Microsoft Blocklist?
Thanks in advance.
Kind regards,
Paul.
