Transfer .mac mail messages to another email client?

Well, you can use other email accounts with Mail (the application). I believe the easiest way to transfer email from one account to another is through Mail. It should be a matter of (while logged onto both accounts) literally dragging your emails from one account on the side bar to another, just like you would move regular files.

As for transferring your emails to a new client, that's a pretty broad question. Mail doesn't have an export function but many email clients have an import function that should recognise Mail's mbox files and be able to copy your emails into themselves. If you're just changing email providers, this shouldn't be necessary.

 

Do you want to transfer your messages to a different client or to a different server? Mail is not limited to .mac. If you want to preserve your messages after your .mac service expires, then you may download them to your local hard drive. If you want to transfer your messages to Gmail or some other free email service, you will probably have to manually transfer them.
