1 - how many domains can I use? I currently use ~6 with my Fastmail account 2 - can I have multiple users? I recognize that fastmail doesn't let me but at this price point I would want it. It looks like you support that but I'm unsure. 3 - How do you convince my ISP to let me receive traffic on the ports required to run a mail server? (most firewall them on residential accounts) 4 - If I were this committed to my email, why wouldn't I just set it up for free myself? This is actually my biggest question in regards to the product/target market. Are there that many people out there that both care about how email works to this degree and aren't willing to host their own?
The website is heavy on theatrics and bold statements but I feel actually kind of lacking in terms of the meat. There's more than a few parts made it difficult for me to get any information at all (the automatic slide show on the Product page, the 'see the inside' slideshow on the tech page). If I had to guess I'd say this site wasn't tested against Firefox (doesn't seem that any are anymore due to its low market sharE).
