News.com reports that Lotus has confirmed the existence of a <A HREF="http://www.news.com/News/Item/0,4,34212,00.html?owv">bug</A> in Notes 4.5 and 4.6 that can expose encrypted email messages. The report offers two ways to work around this. First, administrators should check to make sure that the correct syntax is used to specify the "Mail File Location" in the "Location Document." And, users should click the button to "Encrypt Saved Mail" in the "Mail Preferences" area every time they send an encrypted message.
