Federal law strictly limits the information that online service providers may disclose about their users. However, you should be aware that email messages contain some information about the sender. Web Mail email headers contain an Internet Protocol (IP) address that corresponds to the sender's Internet service provider (ISP).
A line in the email message contains an 8 to 12 digit number, separated by periods like the following example:
Received: from [123.456.78.91] by . . .
The "123.456.78.91" represents the ISP's unique IP address for the sender. After you identify the IP address, you can search to determine which ISP provides this person with Internet access.
If you believe that the spam or abusive email is being sent from one
of our accounts, contact your Web Mail Administrator with the information.
