To me there are these risks to e-mail: 1. e-mail address loss (domain loss, service termination if you don't own the domain, ...) 2. email service loss (server goes down, ...) 3. delivery mechanism compromise (someone gets to read future messages, can be used to hijack online accounts) 4. sending mechanism compromise (partial impersonation, etc.) 5. e-mail archive compromise (someone gets to read old messages) 6. archive loss You have to think hard about each point: - how it can happen, - how would you detect it, - what it could lead to, and then prepare for those circumstances via preventive measures, and by having a plan for when it happens. For example if you register your domains under an account where email that was used for registration comes from one of those domains 3. can easily lead to 1. and you're hosed. You have to have way to restore 2. without access to e-mail addresses that will not work while 2. is happening. You will most probably have no way of detecting 3./4. before bad things start happening. etc. etc. E-mail is not really something to fuck with, because of how important it is for authentication on the web. Helm website doesn't work for me, but if you're thinking about an easy way to have a personal email server, and don't have experience, be careful.
