Network Associates this week will launch its McAfee SpamKiller appliance, which is based on McAfee's WebShield.
The SpamKiller boxes provide scoring, filtering and heuristic detection rules to shut out spam at the internet gateway, said Zoe Lowthere, group product marketing manager at McAfee.

To curb repeated spam attacks, the appliances offer personalised lists to determine both acceptable and unacceptable senders. The product also includes real-time black hole list support capable of quarantining or blocking e-mail.
Many customers, however, will not wake up to the spam problem until e-mail storage or upkeep is severely affected, said Eric Hemmendinger, security analyst for Aberdeen Group.
IronPort Systems will also ship an e-mail gateway appliance which uses reputation filtering to identify the source of spam. The IronPort C60 can capture information about a sender, such as country of origin, and whether or not the sender receives return mail.
Next month, SurfControl will roll out E-mail Filter 4.7, featuring tools to weed out hidden code within HTML e-mails.
Deerfield.com will also introduce VisNetic MailPermit, gateway software to verify a message sender's legitimacy.
