If Microsoft based mail servers have blacked your server’s IP address, you will see something like this in your email server logs or in a bounced email:
550 SC-001 Mail rejected
to fix this issue, you will have to check the Blacklisting status:
- check for blacklist record on MX toolbox.
- if your mail server’s IP is not listed, submit to the Microsoft’s Blacklist reporting program.
- Done.
