Export to Mail.app

No formal tool exists to export your Thunderbird mail to Mail.app on Mac OS X. However, Thunderbird users may have a need to do this for one reason or another. Try the following:

• Navigate to ~/Library/Thunderbird/Profiles/youruserprofile/Mail/Local Folders/
• Identify mailboxes you seek to use in Mail.app.
• Each mailbox has three pieces to it - i.e. "inbox.sbd", "inbox.msf" and "inbox" with no extension.
• Take the file with no extension, hold down the option key (so it also stays in the folder) and drag it to the desktop.
• Rename with ".mbox" as file extension, for example "inbox" becomes "inbox.mbox".
• Open Mail.app and select "File Import", choose "Other" and navigate to the desktop and click "Choose".
• Your mailbox(es) should appear in the import window and will import into Mail.app.

If the above procedure doesn't work, see the Export mail into Outlook (Express) or Apple Mail article.
