Spam Sleuth Enterprise
Helping keep e-mail inboxes spam-free is the goal of Blue Squirrel's Spam Sleuth Enterprise (www.bluesquirrel.com), which is an anti-spam server solution — as opposed to an individual e-mail filter — that resides on an e-mail server or as a separate server to screen out spam before it reaches the internal mail server. E-mail messages designated as spam are never passed along to the e-mail server; thus, they never reach a user's inbox. Administrators receive a report for each spam message that explains why it was designated spam. New features on this version of Spam Sleuth include E-mail Stamps, which charge companies a fee to send spam, and Turing Tests, which force suspected spammers to answer questions in order for their e-mails to be delivered.
