Why do I need a subscription to spam
definitions?
Though the product is self-training, local spam
definitions are developed only by the criteria you input
and from the sample of email messages you process.
Symantec spam definitions are developed from a much
larger set of information and can prevent you from
seeing many of the more common types of spam.
