Delete Duplicates for Eudora 7.4

Delete Duplicates for Eudora enables you to delete duplicate e-mail messages from your Eudora mailboxes. It is a plug-in, i.e. an auxiliary program that interfaces with Eudora (for many people the e-mail software of choice), can operate in and on the Eudora environment, and provides functions that Eudora itself does not provide.
Why the need for this program, since if you see duplicates you could delete them yourself? The answer is that many people now conduct much of their professional and personal communication -- indeed much of their professional and personal lives -- via e-mail, and some people use Eudora as their filing system for correspondence. This leads to a situation in which people have hundreds or thousands of Eudora mailboxes on their computer, containing thousands or tens of thousands of messages, and this can make it difficult or impossible to even spot duplicate messages, especially if they reside in different mailboxes.
