There's a fairly general way to do mail import that works fine with Fastmail, and might be more flexible if you would like to combine the import with reorganization your mail folders. This assumes both providers support IMAP.
1. Set up both providers on an IMAP client that supports multiple simultaneous accounts.
2. Copy messages from the old provider to the new by simply selecting them in the old provider's folders in your IMAP client and dragging them to wherever you want them in the new provider's folders.
As long as you pick an IMAP client that supports copying between IMAP servers, this should do it. I used either Apple Mail or Outlook for this. I don't remember which.
