The dirty details of this presently unfolding scandal do not require repetition on this page. Google will lead you to all that you want (and don't want) to know about these sordid details. However, you won't read much of the following advice in the mainstream media. So, here we go ...
1) Discuss business on corporate e-mail accounts only
The FBI's cyberstalking investigation led to a personal Gmail account, which the government accessed and ultimately resulted in the downfall of General Patraeus. A recent Google transparency report revealed that it has fully or partially complied with at least 90% of the U.S. government's nearly 8,000 requests for user data during the first half of 2012. http://www.google.com/transparencyreport/userdata requests/ The lesson learned is that it is much easier for the government to get e-mails from Gmail, then from your own IT department. This is information that (1) you do not control; (2) might not have notice that the government has requested access to; and (3) do not have say whether the communications are protected by some privilege or confidentiality clause. As a corporation, there are many things that you might want to keep quiet: trade secrets, potential business deals, future products, etc. As Google does not have your company's interests at heart, having employees discuss these developments through personal e-mail accounts could lead to their public disclosure. Further, you would receive no notice that the information has been sought out by the government. Therefore, reminding your employees to keep business e-mails on corporate e-mail accounts will prevent your company's private issues from going public.
2) Be careful who you are e-friends with
While investigating the cyberstalking complaint, the e-mails of the victim led to the discovery of potentially inappropriate e-mails of another senior general who was uninvolved in the original cyberstalking charge. Now that senior general is being investigated. The lesson learned here is that the government, while investigating someone else on a matter unrelated to you, could come to learn information that would place you or your corporation under surveillance or investigation. Therefore it is imperative that not only you keep your corporate and personal e-mails separate (see point 1), but also that you know the person who are sending the e-mails to. A joke in poor taste to someone under surveillance could result in you landing in hot water.
