I am moving a website from one hosting provider to another, and this of course means that I need to migrate all the mailboxes as well.
Do I have to manually move all the old emails from one server to another, or will all the email clients "save" a copy of the old emails on each computer?
UPDATE
Pardon, the naivety - I hope this additional info helps:
I'm doing this remotely, so I am not sure which email client(s) people will be using at the office, but I will need to be prepared for both POP and IMAP setups.
Also, the server they currently have is on VPS.net (cPanel), and we are migrating to a MediaTemple Dedicated Virtual (Plesk). Both Linux.
