i don't see how de-duping can work anyway. right now i have alejandro in my to field, and [EMAIL PROTECTED] in my cc field. there's nothing mailman can do to stop alejandro from receiving the same message twice is there?
Hi Iain,
Its quite simple, each mail message that is sent out had a unique ID (have a look in the headers - The email I am replying to is ID <[EMAIL PROTECTED]> ). Your mail server receives the email directly and via the list. Because the list server preserves the ID, your mail server can easily de duplicate the messages as it knows its already received it.
