Delete Duplicates for Eudora is a program that can delete duplicate e-mails for Qualcomm Eudora.

It features 3 duplicates detection modes:

1. Classic: Entire messages raw contents are compared. Every byte matches, messages are identical. Its somewhat slower & more memory consuming, but reliable.

2. Hash: If this option is selected, DD will compare messages CRC32 values (which is type of digital fingerprint, generated from the message contents). If two messages have the same CRC32 values, those are considered as duplicates indeed. It performs much faster then Classic (on the larger mailboxes, in particular), and its a few percentage points less reliable then perfect.

3. Light: Only "Message-Id" headers are compared. Two messages with the same IDs are regarded duplicates. It may not be reliable since messages are editable in Eudora (and can be changed), but has a mighty execution. If you are dealing with messages that contain lots of text (say over 300K each), and you are positive message headers have not been edited manually, this is _the_ option for you. Note, messages without IDs are simply not compared.
