Tell that to people that live in Colorado, Oregon, Washington, or (mostly) Utah. They've been voting by mail for years. I'd worry a lot more about computerized election systems before voting by mail. I think people are too worried about individual votes/errors. 0.0x% of ballots being lost/not counted/etc. is a problem with any election system ("hanging chads", signatures not matching well, ...), not just voting by mail. The question should be how hard is it to pull off a large scale disruption/fraud without being detected.
