Spam traps catch 95 percent of e-mail sent

Study finds European ISPs successfully managing junk e-mail, partly through dedicating significant amounts of money to the problem.

Less than 5 percent of all e-mail is delivered to mailboxes, as the rest is junk blocked by spam-fighting efforts, according to Enisa, the European Network and Information Security Agency.

The agency reported the finding in a report, published last week, on antispam measures taken by European ISPs in 2009. While these measures are well used by providers, junk e-mail remains a key problem for them and takes up a large part of their annual budgets, according to the report.

ISPs surveyed by the agency said nearly 80 percent of all SMTP connections were aborted, mainly because a match had occurred against a blacklist. Of the connections that were accepted, almost 80 percent were filtered out, mostly as spam, it added in its report.
