As most of you know I work for the Engineering Dept of Cambridge University, mostly dealing with email related things. We have a bunch of people with a shared role account on hermes, the university mail system. They're using two different mailers to access it, and saving messages in IMAP folders. They're nearing quota, and want to archive old material in a format which is accessible (in particular) in both Outlook and Eudora. We have shared filespace, but could do with ideas as to how on earth to store this mail in a way that they can all access it.
So far it looks like the best answer is to continue to run our own IMAP server, so it can be used for such archives. We were hoping to run it down though. Hermes is hoping to provide larger quotas in future (currently at 250MB default, up to 1G, which this team are already allocated), but don't intend it to be used as an archive.
Will write at some point about a) sisters hen-night and b) moving house, but I'm a bit busy at work this week as a result of b) and will be at a course all next week, so it'll probably have to wait til we have internet at home. Suffice to say: thanks to all who helped, and we're very happy.
