First, it specifies how many seconds in the past to check for login failures. Second, after sending an e-mail, update the alert setting "delay between responses" to this value. The alert will then wait for the specified number of seconds before responding to additional login failures. * @EmailRecipients - List each e-mail address that will receive the message and separate each address by a comma. * @SendAlert - This variable returns the value "YES" after sending an e-mail.
