There is a retrieve button for that e-mail you sent in error, but it seems you have to obtain a court order.
Goldman Sachs Group Inc (GS.N) on Wednesday said Google Inc (GOOGL.O) has blocked access to an email containing confidential client data that a contractor sent to a stranger's Gmail account by mistake, an error that the bank said threatened a "needless and massive" breach of privacy. The breach occurred on June 23 and included "highly confidential brokerage account information," Goldman said in a complaint filed on Friday in a New York state court in Manhattan.
Goldman did not say how many clients were affected. It has been seeking a court order compelling Google to delete the email, which it said on Wednesday had yet to occur.
“Google complied with our request that it block access to the email,” Goldman spokeswoman Andrea Raphael said. “It has also notified us that the email account had not been accessed from the time the email was sent to the time Google blocked access. No client information has been breached.” A Google spokeswoman declined to comment. Google Issued With a Court Order To Block Goldman Sachs E-mail Sent In Error [reuters.com]

So, a dead-ish account then, assuming it took more than a few hours to stir the laywers into action and for G to respond.
Had it been sent to one of my clients it would be on at least one of their machines by now, probably in the trash bin. :)
Have to say: if goldman or any of their contractors uses a public mail service they are asking for trouble anyway. I've killed access to our web sites before now from IP ranges registered with a public address. Very unprofessional!
