Hi

I found on dbmail wiki following passage:

> Ability to store only a single copy of duplicated mail messages to
> save storage. (update: this was done already in 2.2 and trunk. It's
> called suppress_duplicates in dbmail.conf)

AFAIK, suppress_duplicates works only when same message is delivered to
the same mailbox. If same mail is delivered (or copied) to another
mailbox, it is copied (and this is good) and not suppressed. But what
author of the original message meant, that 2 identical messages inside 2
different mailboxes should not take double space. This is same idea as
hardlinks on filesystem.

Is there something like this in dbmail?

BTW, suppressing duplicates in a way it is implemented now is sometimes
misleading. Try, for example, to delete a message and add it again when
suppress_duplicates is enabled - message will not be added. This happens
because message is still in database and is only marked for deletion,
but for enduser this is not so clear.
