Hi Team,
Since last few days I haven't been able to send any emails to hotmail ids.
It's showing the following error message:
ERROR_CODE :550, ERROR_CODE :5.7.1 Unfortunately, messages from [103.117.158.53] 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. [VI1EUR05FT006.eop-eur05.prod.protection.outlook.com]
Kindly help me in resolving the issue.
Thanks in advance.
Regards,
Harsh Rakani
