Save Messages to mbox File
As an alternative to rescuing messages, you can save messages to an mbox file and import them into your email program. This can sometimes be faster than emailing the messages to your in-box, especially if you have a lot of messages to rescue.
To save a message to an mbox file, open the message or select the message in the Spam List and choose Save As... from the File menu. You can also select multiple messages in the Spam List and save them all to a single mbox file.
Be sure to save the file someplace where you can find it later. The desktop is always a good place to save files.
The mbox file format is a cross-platform, cross-program way to store email messages. Most email programs can import mbox files very easily.
