# Kill List File

The kill file lets you specify a mail address or a particular mail host that you do not want to accept mail from. In this case, it will prevent the host or addresses from posting to the selected list. The KILL.LST file is located at IMail\Lists\(Listname) and applies to the primary host and all virtual hosts.

The KILL.LST file is used by

- The SMTP server to deny access to the mail server.

- The List server to deny access to local mailing lists.

## Adding an address to the Kill File

Enter the address in the text box and click Add.

You can enter addresses in either of the following formats:

userid@host

@host

For example, to deny access from a user mail account, you could enter: fred@widget.com To deny access to all users from the mail host widget.com, you can enter: @widget.com

IMail Server checks the incoming message's From <user@host> line. When it receives mail from an address listed in the kill file, IMail Server returns the message: "501 unacceptable mail address"
