A new study from IDC concludes spam levels will be higher than real person-to-person e-mails in 2007.
Mark Levitt, IDC VP of enterprise workplace research, attributed part of the growth to new ways of bypassing spam filters. "Spam volumes are growing faster than expected due to the success of image-based spam in bypassing antispam filters and of email sender identity spoofing in getting higher response rates," he said.
However, more of the higher spam-to-P2P ratio will come because personal e-mails are being replaced by instant messaging and voice-over IP (VoIP) applications, said IDC.
They also say businesses will send a total of 5 exabytes (5 billion gigabytes) of e-mail this year - that's more than 2005 and 2006 combined.
