If you believe your provider is untrustworthy, mail storage is a small part of your problems. An untrustworthy provider doesn't need to run the mail server to watch the traffic to and from it. Encryption helps a little, but that's true even if you used a provider's mail server. Encryption is difficult for most people to do well. If you put a personal server in a co-lo, remember the co-lo provider potentially has physical access to your equipment on their premises.
In regards to having one's server in co-lo facilities, one can ensure their server is guarded by either having the machine startup with a password. Should some provider attempt to reboot into some form of shell it would still take some time to break a password and get in the machine. By the time (if the right measures were taken) your server went down, if you had proper monitoring on the machine, you would know and hopefully you would go on to auditing your machine. Otherwise it would take minutes to reproduce your disk which is threatening considering anyone possibly a competitor could access some sensitive information using tools small enough to hide under their arm. (http://ics.forensic.e-symposium.com/computerforensics/) This reminds me of the security at what used to be Exodus in Jersey City. Back in 1996 I worked for one company through 1999. In 99 I went to work elsewhere for a company with co-lo machines in the same facility. Of course I went through the rigorous ID'ing of proving who I was, where I worked along with all the fax information etc., and wouldn't you know it, short of stopping to take DNA samples, Exodus staff badged me with my previous employers information. When the keys were handed over I responded I no longer worked there. Go figure.
On the other hand, if your trust your provider enough to believe it will conform to the law and contractural arrangements, you may make a rational choice to rely on the service provider to maintain a mail server instead of trying to maintain one yourself. Some people hide their money in a mattress in their house, other people keep valuables in a safe deposit box at a bank.
If it's your own business, I personally feel you should take your own steps to ensure your data is protected. No one else will do the job you want. You might get all of the soupy sales talk, but the work will to some degree be subpar. One of my petpeeves with my current location is they're relying on Postini for filtering. Sure Postini does so and so filtering, but 1) they don't even use SSL, 2) they're configured to know our users' passwords and usernames which is horrible. I argued about doing our own RBL's and filtering even blocking entire subnets but some of our loony customers have called with even loonier comments such as "Is there a problem on your network today? I haven't gotten my spam" (not kidding) Being I'm just your *.Corp lacky and have become tired of rambling on, I laugh it off when poop hits the fan with a silent "told you so."
US law may still be developing in the area of stored electronic information in comparison to physical storage. US Supreme Court Justice Marshall said in Couch (1973) "Placing [records] in a safe deposit box is different from letting them remain for many years with an accountant." In the electronic world how different is storing a file on a floppy disc in a physical safe deposit box of a bank for more than 180 days different than storing the same file online in an "electronic vault" of a Internet service provider for more than 180 days?
If I'm not mistaken Sarbanes Oxley placed some really harsh standards for providers. I started reading through some of the issues on the tech side of that law, but am still catching up on CALEA, CHIPs, and other fuzzy little acronym(aged) laws that sprout up like nasty weeds =+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ J.
