Corporate email systems under pressure from spam and staff abuse

"More than half of corporate email messages are not work related, but rather either spam or personal communications, new research has claimed. According to a study published today by Radicati Group, 23 percent of all messages in respondents' corporate mailboxes were personal and not work related in nature. The consulting and market research firm coupled this new study with data from an April 2005 survey that found that approximately 33 percent of corporate email is spam. Thus, the firm concluded that over 50 percent of email residing on corporate servers is not work-related." No wonder it is getting harder to filter spam. Source: scmagazine.com
