Hosting Recommendations

I need to find a good email/web hosting service. Yes, this is on-topic. Right now, subatomix.com (my mail server) is a machine in my house, connected via residential cable modem service. This has some cool factor for me, but there are disadvantages: (0) The system has to up and stable 24/7; I can't play with it in ways that might interrupt that. (1) The cable modem connection goes down every now and then, sometimes for several hours. (2) I'm not too knowledgeable at mail administration; there's a good probability that this machine is not as secure as it could be. On top of that stuff, a credible source inside the cable company says that I will be eventually switched over from RoadRunner to the cable company's own network. According to the source, areas where the switches are occurring (mostly those served by @Home, but RoadRunner is next) are experiencing repeated, prolonged outages. So I need list members' recommendations on a good email/web hosting service. If you work for such a service, feel free to suggest it if it is a good service. What I want is: (0) Email hosting for 5 addresses at subatomix.com. It needs to handle several hundred emails per day (peak) and the occasional large file mailed to me. (1) Web hosting for my as-yet-unfinished personal web site. The largest part of the site will be an exposition of my collection like that of many others here. I plan on having a lot of pictures, and the service needs the capacity to hold them. (See it *is* on-topic). (2) Encrypted communications, or at least my passwords not sent over the network in cleartext. (3) The servers running some UNIX and administered by competent people. (4) A flat fee. (5) If I use their DNS servers, the ability to point foo.subatomix.com to a certain IP address. -- Jeffrey S. Sharp jss(a)subatomix.com
