I can use tools to find duplicate Message-IDs, but don't know of a way to remove duplicates in mailboxes that are already imported as opposed to incoming mail. Perhaps there is a way to use the IMAP protocol for this?

Saved about 200M in one particularly large mailbox. Thanks!
Thanks to others for their suggestions, now working with delIMAPdups since I have mails (not many, but a few) which have identical content and are only different in their Content-Type header lines. One copy will have the declaration on one line, the other has its declarations folded across multiple lines for each parameter. Any idea why *that* might be?
