Send someone an email... in 100 years

Someone asked me recently if I would want to share all the details of my life with family members. "Only posthumously," I answered. My e-memories are for me alone, as least long as I live.

Now, in an email twist on this posthumous impulse, MailFreezr.com offers to store your email and deliver it to a designated recipient after a given number of years - up to 100. I wonder how many confessions will be in that server?
