I currently run my own IMAP server and I have decided to move a domain email service to Mail-in-a-Box. I have bought the vServer to host mail-in-a-box and now I need to setup mail-in-a-box. All seems easy but before I start I would like to know how to migrate the current emails I have into the new server? Once I move the DNS of matos-sorge.com (my domain) to mail-in-a-box I will lose my previous emails. What’s the easiest way to transfer all the emails between servers?
