Mainz - Most daily e-mails are not sent between friends or even business partners.

Instead, 92 per cent of e-mails sent between January and March 2008 were spam, according to Sophos, a Mainz-based information technology security firm based that regularly monitors internet mail.

The United States remains the world champion when it comes to spam as more than 15 per cent originated there.

Sophos did not track the number of spams actually reaching the mailboxes of internet users. (dpa)
