We host websites and email for a variety of clients. We're looking into the possibility of offering an email backup service, whereby every year we send our clients a copy of all their email over the last year, on a CD / DVD which they can put in their computer and browse should they need to retrieve old emails. I think I know how to route all incoming and outgoing emails to a suitable place for backup. Our server runs Exim and emails are stored in the /cur/ folder for each email account. So I know where the emails themselves are, and can burn these to CD.

I'm now looking for a suitable freeware .exe program I can include with the CD to give customers a browseable interface to these emails. Something that would run on autoload when they put the CD in the machine.

Does anyone have any suggestions or is this just crazy talk?

Many thanks,
