Some salient numbers from the reports:

• The Barracuda Networks study, based on an analysis of more than 1 billion daily e-mail messages sent to its more than 50,000 customers worldwide, found that 90 percent to 95 percent of all e-mail sent in 2007 was spam, increasing from an estimated 85 percent to 90 percent of e-mail in 2006;


• Barracuda Networks' poll also showed that 50 percent of users received five or fewer spam e-mails in their in-box each day. Almost 65 percent received less than 10 spam messages each day, while 13 percent were inundated with 50 or more spam e-mails daily. (That's me, unfortunately.);


• Spam is becoming more sophisticated. Barracuda Networks found "that the majority of spam e-mails in 2007 utilized identity obfuscation techniques";


• Spammers also increased the usage of attachments, such as PDF files and other file formats in 2007.

• 57 percent of respondents view spam e-mail as the worst form of junk advertising, close to double the 31 percent that cited postal junk mail. Only 12 percent chose telemarketing;
