My email was rejected. Why was I sent here?
First of all we are sorry to bother you. In fact your mail is not bounced to annoy you. We'll try to explain what's happening here.
The email server that you use for sending email is probably listed in our Open Relay DataBase (ORDB). Your email server can easily be tricked into sending large amounts of unsolicited email, called spam. The email server is a so-called "open relay".
System administrators all over the world choose to use our database to refuse mail from such servers, until the server has been fixed to stop relaying spam to innocent users.
Sohere's what you should do: Contact the system administrator of your mail server and forward him a copy of the bounced email you received. The standard system administrator email account for an Internet mail server is "postmaster@your-domain.com". For example; If the name of your ISP is Big-ISP.net then forward a copy of the bounced email to "postmaster@Big-ISP.net". Otherwise, you should call tech support and alert them of the problem.
If the server is owned by your school or employer, thencontact your support department and explain the same thing to them.
We know that email is important to you, and we want to help your ISP resolve the problem of your mail bouncing. Correcting this problem is usually a very simple process, involving your ISP changing a few lines of one configuration file, or ticking a checkbox
