It may seem like spam has always been with us, and unsolicited commercial email (UCE) did arise in the early days of the public internet—followed not far behind by outright criminal messages that tried to steal credentials (phishing) or install or pass along malware.
SpamSieve is nearly two decades old, arriving on the Mac not too far after spam first became insufferable. Its advent was near the beginning of the Mac OS X transition. It arrived after a certain kind of frequency analysis became a popular way for server software to distinguish spam (unwanted email) and ham (the good stuff) with some reliability.
The app uses Bayesian inference, which is the mathematical equivalent of an educated guess based on which words or phrases appear more frequently in mail you want and mail you don’t. (It’s used broadly across many disciplines—not just email quality detection.)
SpamSieve scores every word and some aspects of embedded images by how frequently they appear in messages marked as spam or ham. As you train SpamSieve’s filter, it increasingly identifies messages as good or bad more accurately. After training my filters for years, SpamSieve is often 100 percent certain a message is desirable or that it’s unwanted, and it’s correct nearly all of the time.
Spammers years ago developed techniques to partially defeat Bayesian analysis—in case you wondered why some spam has extracts of random passages of text at the bottom—but there’s only so far a message can go in defeating probability before it’s unreadable by a recipient. And SpamSieve includes other filtering options, like an option to block all HTML encoded to be unreadable to the human eye until viewed in a browser.
SpamSieve is a largely set-it-up-and-forget-it utility after some initial training, about which C-Command Software offers detailed guidance. A tip: save spam you’ve manually identified for a bit so that you can prime…
