I m getting this error from last 22 days but still did not get any update from customer care. I spoke with the technical support team for more than 3 hrs but still did not get any solution yet, I switch in GO Daddy because I thought this is well known but Unfortunately, I was wrong and now I m thinking to change from go daddy to some local.
The error message you are seeing is caused by a suspension on your hosting plan. Sending email from your hosting plan has been restricted due to abuse or sending spam. You will need to take action on your hosting plan to resolve this, usually by updating your site and removing any issues. You will then need to continue working with Support to have the restriction lifted.
