Are Spam Blockers Too Strict?
America Online's controversial plan to charge mass e-mailers a fee to bypass their anti-spam system highlights the other, lesser-known, horn of the junk-e-mail problem: Filters that allegedly work too well.
At issue is the problem of "false positives," industry-speak for legitimate messages mistakenly filtered out by anti-spam software.
"If AOL or another ISP decides that someone's a spammer, then no e-mail from that individual gets through," said EFF attorney Cindy Cohn, whose group opposes the AOL plan. "But there's a fundamental difficulty at the heart of the spam debate: The only one who knows what you want delivered in your inbox is you." For years, e-mail users complained that torrents of unwanted messages clogged their inboxes and crimped their productivity. Now, e-mail users, marketers and mailing list operators are more worried that spam filters are blocking out too many wanted messages.
