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?
