No, not as Exim stands. Normally this sort of duplicate suppression is
done in the storage system, rather than holding mail in the spool for
longer.
This is known as "single instance store", at the message-level rather
than the attachment level. It will work unless the mail service
provider is also rewriting Subject: headers for each variant mail.
Cyrus IMAP will do this by default; it looks as though Dovecot might
only do this for attachments, as an extension, but I don't really know
Dovecot and could be wrong.
