Server at home or use a hosting company?

MediaTemple looks pretty good. It’ll be another 2 months before my site

goes to production. If you could give me feedbacks on MediaTemple’s
grid server, I’d appreciate it.

I don’t know much about server/network configuation and here’s my
question - Let’s say my domain is
mysite.com
. Is it possible to set up
my website at one ISP and have my mails for the website, e.g.
help@mysite.com, set up at another ISP? How does that work? If I end

up going with a VPS, I’d like to dedicate that VPS to my website and use
another ISP for the emails of my domain. Is that possible?

Thanks.

Yes, you would just change the MX record for the domain.
