Brightmail spam definitions not updating

Early registration is now open for Office3, the annual online gathering of IT Strategists, Microsoft MVPs and Messaging Technology Vendors.

It can be centrally managed through a multi-server console.Traditional signature and heuristic file scanning engines form the backbone of Symantec’s security solutions; these engines use dozens of techniques to scan files for both known as well as unknown threats.Technologies designed to block attacks just as they transition from the network cable or wireless network to the computer, before they have a chance to establish residency in a physical file on a user’s computer. Behavioral-based protection technology observes actively running threats on your computer and can terminate running programs if they exhibit malicious behaviors; this technology provides proactive protection from entirely new, previously unseen attacks. Sender then kills the TCP handshake of offending IP addresses, conserving bandwidth in the process.Iron Port packages the C-Series solution with another piece of innovative technology: Virus Outbreak Filters (VOFs).Few things to note if you do have error while updating the Cloudmark engine.

If your server doesn’t have a proxy requirement, uncheck the “Enable Proxy Server” option in Forefront Management Console and save the setting.

One thing I noticed after configuring the platform is that both Cloudmark and Worm List engines rarely update.

A quick google highlighted the fact that many are facing the same issue and hence I looked more into the issue.

Although Iron Port Systems' Iron Port C-Series Messag-ing Gateway packages solid third-party antispam and AV tools into one e-mail solution, it's the appliance's proprietary next generation spam-fighting technology, Reputation Filters, that really makes it something special.

The Reputation Filters approach is similar to white-lists/blacklists, but the rate of false positives is much lower.

One caveat: VOFs and Iron Port's bundled third-party tools (Symantec's Brightmail Anti-Spam and Sophos' Anti-Virus) are all optional buys based on per-user subscriptions and can quickly add to the cost of the basic appliance.
