Deleting duplicate email messages?

I'm cleaning up slightly different versions of some Eudora mailboxes that
were restored from backup from various dates. I have two slightly different
versions of a mailbox with thousands of messages where there is a lot of
duplication of messages between the two mailboxes. Poking around on the
Eudora site, it seems there used to be a miscellaneous option to delete
duplicate messages, but it doesn't seem to be there anymore. Does anyone
know of a good way to merge the mailboxes and delete the duplicates -
through Eudora, CalMail IMAP boxes, Bearmail, or an independent tool?

Does anyone have any experience with the "Delete Duplicates for Eudora"
plug-in for Eudora which I have stumbled across? Or have a warning about
Eudora plug-ins in general? You can find information on this plug-in on
these sites:
