emlx, eml - email files
Email can contain all file types encoded in base64. File Juicer can extract attachments, and it is not limited to the usual formats available in the preferences.
Using Mails normal save procedure may be preferred, as the file names can be more correct that way, but this may not always be possible.
File Juicer has been tested on Apple Mail, and on EML files from Microsoft Outlook Express and Yahoo Mail.
