OnlyMyEmail

Reviews say OnlyMyEmail does a good job of filtering out spam with fewer false positives (the misidentification of legitimate emails as spam) than many other anti-spam products, but at a higher cost. OnlyMyEmail is a web-based spam filter, which means you don't download anything, saving hard-drive space. For a monthly fee of $4, you direct up to two email accounts to OnlyMyEmail, which filters your mail and sends the non-spam to your OnlyMyEmail email address. You also receive a daily list of blocked messages that can be rescued from OnlyMyEmail for seven days. In one test by PC World, OnlyMyEmail failed to recognize spam only 11 times among more than 3,000 mostly spam emails and registered just one false positive. If you don't want to spend any money for a spam filter, however, reviews suggest Spamfighter (free), though the trade-off is annoying ads.

Professional reviews of OnlyMyEmail are flawed by being old -- spammers haven't stopped tinkering since PCMag.com and PC World reviewed OnlyMyEmail in 2005 and Smart Computing weighed in a year later. We found a 2007 blog entry by a technology writer in which he appears to be in the wrong in his dispute with OnlyMyEmail, but his descriptions of service outages are worth a look.
