Hidden code in e-mail messages is increasingly being used to track the success of spam campaigns, according to a warning by an antispam technology company.

The company says renewed awareness of the spam beacon problem is needed because most e-mail users don't realize that they are being tracked by spammers. Also, many e-mail providers are not interested in stopping a "feedback loop" that lets spammers improve their art.
