It really needs to be said that email, even though it seems to have an inherent mechanism of persistence, is a really very high, thorny, technical load to assume. As someone who cut his teeth on email-server administration in the early days of Sendmail, I'm still kind of puzzled at the lack of coherent solution to this problem - it still seems as though the cognitive load behind setting up and maintaining a functional mail server on todays Internet hasn't changed much since the days of !uucp!myfoo!me .. but is this really the case?
