The kill.lst file is used by the SMTP server to deny access to the mail server. It allows you to specify mail addresses or mail hosts that you do not want to accept mail from. The kill.lst file is located in the IMail top directory and applies to the primary host and all virtual hosts. To create or edit the kill file, click the Edit kill file button. The kill.lst file appears in Windows Notepad, or if no kill.lst file exists, one will be created.
In the KILL.LST file, enter one entry per line in either of the following formats: userid@host
To deny access from a user mail account
To deny access to all users from the mail host widget.com
The following will reject all mail mail from widget.com, bluewidget.com, and nifty.widget.com.
Note: The SMTP kill file is separate from the kill files for Lists.
