When a mail client sends mail, the server that receives it adds at the top a Received: line that contains the IP address of the client. This also includes servers, if they decide to forward the mail elsewhere. So the headers contain one or more such lines. The first line that is added by "your side" of the transfer contains the address that you are interested in. Search whois for this address to find out what ISP registered it. -- Didi ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
