I went and had a look at it last month - as well as some of the competition. In the end, none of them would've been suitable for what I wanted - POP access. So for me, I get to figure out how to implement my own mail engine.
When I did visit Everyone.net, though, it was horribly slow, even taking into consideration the fact that I am in Thailand. I'm not surprised that sometimes the setup/config area goes down - the same happens with Reporting.net. IMHO, that's inexcusable - for companies providing such large-scale services (including Ebay) it is a must that they have backup systems and networking which will allow continued operation.
Needless to say, I won't be using Everyone.net anytime soon - but I certainly hope they resolve their problems quick so that you can continue to do what you set out to do.
