I'm building a demo computer for presentation. The demos require to send / receive emails for some demo users (3 or 4).
What is the simplest, free way, to have a local mail server (pop or imap and smtp) ?
As it's a demo computer, I don't care about security, performance, advanced features, etc. The only requirement is that the solution must be light as I'll run a lots of apps on the single computer.
FYI, the demo computer won't have internet connection, and is running Windows 2008 R2 x64. The target client is Outlook 2010 X64.
