Is there a way to deliver the same Mail in the same Mailbox only once ? Yes this case is supported via an sieve extension: require ["duplicate"];
#Deduplicate mails sent to aliases for same mailbox using the msgid if duplicate { discard; } I wouldn't do that. Message with the same message id doesn't need to be duplicates. See the difference between this message (I put you on BCC), you'll receive it via the mailing list AND directly. Depending on the ML configuration the messages are NOT identical.
The "duplicate" test allows more complex arguments to handle such concerns. This way, for example, the list-id header (if present) can also be part of the unique ID used for duplicate tracking.
