Microsoft's email service consists of hotmail.com
, outlook.com
, msn.com
and live.com
domains. As this is a very popular email service, you may eventually experience an issue within your server/network that resorts in you getting blocked by Microsoft due to undesirable email habits. This could be due a number of things.
Ex:
When you do find yourself blocked, you may see some error messages such as:
550 SC-004 Mail rejected by Outlook.com for policy reasons. A block has been placed against your IP address because we have received complaints concerning mail coming from that IP address. We recommend enrolling in our Junk Email Reporting Program (JMRP), a free program intended to help senders remove unwanted recipients from their email list. If you are not an email/network admin please contact your Email/Internet Service Provider for help.
550 5.7.1 Unfortunately, messages from [xx.xx.xx.xx] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [HE1EUR04FT063.eop-eur04.prod.protection.outlook.com]
