GFI launches freeware version of Exchange Server anti-spam product
As a contribution to the battle against spam, GFI today launched a freeware version of GFI MailEssentials for Exchange/SMTP 8. The free version allows incoming email to be checked against popular DNS blacklists (also known as real time blacklists) at server level, prior to distributing the mail to network users. It also enables administrators to set up their own blacklists and includes a patented automatic whitelist management tool.
