In Symantec Mail Security, a separate email that can be automatically sent to the sender, recipients, or other email addresses when a specified condition is met.

The Notifier message (notification) is customizable; it can contain a list of the subject lines and senders of all spam messages. A dynamic list of IP addresses of identity-masking relays, including proxy servers with open or insecure ports, provided by Symantec based on data from the Probe Network. Because open proxy servers allow spammers to conceal their identities and off-load the cost of emailing to other parties, spammers will continually misuse a vulnerable server until it is brought offline or secured.

A unit of data that is formed when a protocol breaks down messages that are sent along the Internet or other networks.

Each of these packets is separately numbered and includes the Internet address of the destination. Upon arrival at the recipient computer, the protocol recombines the packets into the original message. A value that is assigned to a variable. In communications, a parameter is a means of customizing program (software) and hardware operation.

An attempt to illegally gather personal and financial information by sending a message that appears to be from a well known and trusted company. A phishing message typically includes at least one link to a fake Web site, designed to mimic the site of a legitimate business and entice the recipient to provide information that can be used for identity theft or online financial theft. A program that system administrators and hackers or crackers use to determine whether a specific computer is currently online and accessible. Pinging works by sending a packet to the specified IP address and waiting for a reply; if a reply is received, the computer is deemed to be online and accessible.
