The best tool I have is the IMAP Backup and Migration Software from eSoftTOols. One of the better tools for this job is this. A wide range of capabilities are included in the software to facilitate email backup. With the mail filter tool, you can extract emails from an IMAP server between a certain date range.you can convert your data into many file formats, EML, PST, EMLX, HTML, MHTML and MBOX files.
