Of course, you may > lack the experience of dealing with large companies. The fact a large company does it doesn't make it any less stupid. And you think a large company could afford their own mailserver rather than making their people use Gmail (now wrap your head around the concept of "confidential mail anywhere *near* a Google-owned server"... ;) To pick up on a part of the sig that Nick didn't rip into publicly: > "and delete it from your system" Presumably, Tremaine, in his self-claimed role as "Security Consultant" *and* "Paranoia for hire", realizes that it quite likely sat on my site's main mail server for anywhere from several seconds to several hours (in fact, there are probably copies on *3* different servers in our mail cluster) - and that until some *other* piece of mail happens to land on those same blocks of storage, the text is quite easy to recover by any decent computer forensics practitioner. On the other hand, actually going in and overwriting the affected block(s) is quite challenging, especially when it's a 10 terabyte mailstore handling several million messages a day for 100K users. We'll be happy to do it - *IF* Tremaine's company is willing to indemnify us for the downtime. So there's 2 possible outcomes here: 1) The request has zero legal standing, and Tremaine's company is relying on the kindness of strangers rather than using PGP or S/MIME to actually secure their mail. This sort of thing is usually called "lack of due diligence", and I don't think any company wants to be flaunting it. 2) The request *does* have legal standing - in which case Tremaine's company may indeed have some liability to pick up any and all associated costs. Particularly interesting is the legal question of what happens when a "please delete all copies" request is attached to something that's sent to a company that is required to retain copies of *everything* for regulatory compliance (as is true for some financial-sector companies).....
