[Evolution] Looking for a Plugin to delete duplicate mails!

[Sanjay Arora <skpobox hotpop com>]

Hi all

I am using Evolution v. 1.2.2-5, on RH 9. I have a small bandwidth cable
connection that often chokes and emails are sometimes downloaded
multiple times. It is a pain in the neck, especially in the case of
mailing lists.

Does anyone know of an evolution plugin that can delete the duplicate
(one or more copies of them) mails using the unique message id. If not,
what do I need to do to achieve this?

With best regards.
Sanjay.
