A couple of companies that we host mail for have been acquired by other companies that have their mail servers and such. So far the mail (and user accounts that take away from our available licenses) have been sitting on our mail server. One they occasionally check and the other I haven't seen a login for a few months. I know for at least the one company, they do want all the email for those users "at some time in the future." Well I want to free up the user accounts, mail store space, etc. Right now I do not know what mail servers these sites are using but I'm going to assume it's not kerio.

What would be the quickest and most universal way to gather up all this email that we can just throw on a dvd-r and send them? And by quick I mean man-hours, not machine-hours. So I guess is there a conversion script that will take a user's mail (the calendar and contacts and such are not a concern) and convert to some 'universal' format, such as maybe .mbox files or something? I was thinking of just enabling ETRN for those domains and have their mail admin just pull the mail into their server, but I'm relying on the not knowing anything about ETRN or any IMAP-to-IMAP transfer tools and just want the files.

Kerio's mail format looks like a modified version of Maildir, or at least one I'm not used to seeing. Could it also just be as simple as taking all the messages, renaming the extension to .eml and be done with it? thanks for any input.

Three methods come to mind: allow the remote mail admin IMAP access so he can simply imap the emails to his mail system (or users mail box). Or imap the emails yourselves into an Outlook pst file and send that over. Using Outlook/KOC you could even create a pst with also all appointments, tasks and contacts. All require some manual effort per user, that may be a problem if it concerns dozens of users...

But if all they are interested in is the emails for legal/archiving purposes, you could just copy the relevant part of the store to DVD and send that over. All emails are individual eml files. Readable by any text reader (notepad?).

imapcopy or imapsync will transfer email between two imap servers easily if you know the account information on both servers.
