MailMigration works with Mac OS X Mail 2 to migrate mailboxes and messages: - form local mailboxes to an iMap server, or - from an IMAP server to local mailboxes, or - from an IMAP server to another IMAP server. Its also possible to only migrate the mailbox structure sans messages. This tool is especially useful when migrating to a different mail server.
There is only one window. It has a source and a destination section. In the source section select the account and mailboxes that are to be migrated. In the destination section select the account where mailboxes and message should be copied to. Messages are always copied, never moved.
