all mailing list software that i found, targeted linux or unix-like operating systems the only option i found for windows was listserv which cost 2K and up .. getting approval for a $2000+ .. at least where i work, needs a super solid business case .. i would argue that at this cost, maybe i should as for a linux box, but then again, who will admin that, who will install and admin postgresql (as an example of a dependency of some of those mailing list softwares) (https://en.wikipedia.org/wiki/List_of_mailing_list_software https://en.wikipedia.org/wiki/List_of_mailing_list_software)
