I'm trying to set up an email distribution list for my wife's inordinately large family (150 people or so) who all have email addresses from different domains. I was thinking about using the free version of LISTSERV (http://www.lsoft.com/download/listservfree.asp), but I don't actually have any sort of server to run it from. The thought has crossed my mind to run something like this off of Raspberry Pi. Would it be possible to do this? I'm assuming I'd have to install a version of Unix first, but I'm pretty new to this.
