* I've just created an alternative that implements something similar to the Procmail code you posted above, but from within Sieve itself. It is a custom language extension called vnd.dovecot.duplicate and it adds the "duplicate" test. This test keeps track of which Message-IDs it has seen before in earlier deliveries and yields a true result if the message was seen before, e.g.:require "vnd.dovecot.duplicate"; if duplicate { discard; }
Interesting... I'll have to look into this later to see how it might be leveraged only for deduplicating mailing list messages (suppress duplicate messages when someone is a member of multiple lists that are members of other lists - I use mailman currently).
