spot price means if you get out bid partway through your hour, you lose that VM and anything running on it (I think there is an option to dump to a s3 bucket or some such - but regardless)

the price is usually so cheap that it's perfect for throwaway computational tasks - hadoop, grid (keep track of the state of your returns independantly), etc, and so on. Also, IIUC it only hits you when demand is larger than supply.

Typically you want a mailserver running 24/7, so about 750 hours every
month.

Do you mean, you have a box, working... then you get outbid and lose a
working box?
