For consumers, spam represents a constant nuisance interfering with regular email. Alternatively, it could refer to a trademarked “spiced ham” of dubious culinary value, which provided the etymological basis for the email variety. For businesses, spam can prove disastrous: flooding potential customers with unwanted ads and associating the company’s good name with sleazy, fly-by-night products. Anti-spam software acts as a solution to the spam problem, though businesses need to apply it more judiciously than individuals. Properly utilized, anti-spam software can spell the difference between a well-run system and an active liability.
Anti-spam software applies “filters” in an effort to spot spam. In the early days of the Internet, these filters were fairly simple: searching for black words on a black background, for instance (a common trick with early spammers) or analyzing email trends sent out from an individual address. But spammers have grown more sophisticated over time and anti-spam software has risen to meet the challenge.
Today, spam filters utilize complex algorithms help businesses keep spam at bay. Sender Policy Frameworks detect the use of forged names and false addresses. Challenge-Response systems, conversely, use “approved lists” of senders and checks any emails sent from those now on the list. (This works extremely well for internal email issues within a given business.) Other filters look for key words (such as pornographic terminology) or “bot” algorithms that clearly originated with an artificial program to prevent the spread of spam. Of course, this all comes alongside real-world techniques such as anti-spam legislation and criminal prosecution of spammers to discourage the practice.
When choosing anti-spam software for your company, it pays to know which methods the software uses to discourage spam. More importantly, software packages need to grow and evolve as spammers utilize new tricks.
