I have the domain for the village that I live in. I never got around to building a site as there are already other sites doing a reasonable job on not so good domains. It seems a shame to waste the domain, so I thought about offering personal email addresses for a fee (not a new idea) but with all proceeds going to local causes. I have asked a few friends locally and all are very receptive of the idea. We live in a large village with a very strong community, indications are that I will easily get a minimum of 100 people paying an annual fee for their email address, (one guy alone has agreed to have 4 for his family and one for his band) which will generate a reasonable amount for local causes. What I need is a recommendation for suitable email software that will minimise the input required from me and that will make users feel comfortable that their personal emails are not visible to me. I'll be very grateful for any suggestions you might have.
