What would be the issue? Is it any more likely to go farbot than a more beefy machine (probably less, due to the lack of moving parts). Never mind that the author is using it to backup his email. It would probably run some kind of fetchmail script as a cron job and caching it locally, so that you don't have to keep a full-fledged computer running all the time. And once that's started up, the backup could easily be downloaded, so that you store your data on several machines. Pretty common setup, people do stuff like this quite often with their routers.
