Only if you are happy to loose data on power failure.
I don't know the actual setup, but if you have no UPC you shouldn't host email services anyway.
I'm guessing you meant UPS, anyway, a UPS wont protect you from human error.
Also, most buildings, at least in this country, have a fire emergency shutoff requirement, meaning mains is isolated from the building, and the back up gennies are also forbidden to be engaged - UPS's dont last forever.
Guys, please don't argue on kindergarten level. The UPS is for backing a sudden death, but not for running five days. Of course you can do a controlled shutdown if battery level falls below a trigger value. And this is about all you need: control. There is no fs error as long as you perform a regular shutdown. If UPS-backup is forbidden in your country then I suggest moving to civilized regions of the planet ;-)
