The email client program sends the command to delete downloaded
emails from the server only after ALL emails have been successfully
downloaded. Sometimes there is a corrupted email on the server
which prevents the download from finishing, so the delete command
is not issued, and the same emails will be downloaded on the next cycle.
To fix this, you will have to use your provider's web interface (webmail)
to look at the emails sitting on the server. The stuck one will typically
be the largest, and will need to be deleted.
