A reply from a mailing list isn't a "real" duplicated mail. Not only that the receiving time differs to the send time, that might be ignored, but "From:" and "Sender:" of the mailing list's mail differ inside this mail, already without comparing it with the sent mail. The body, subject and the used servers of the sent email differ to the one received from the mailing list. The mailing lists email also does include mailing list information, an ID, how to receive help, how to unsubscribe etc. (it's not only mentioned in the footer, the body's signature). IOW the reply of a mail we sent is a completely different email. Many people ask how to unsubscribe, if they would send a mail and could receive their own mail, that came through the list, even without a footer, they would get the information inside the emails header. So, a duplicated email can't be identified by the thread informations inside the header only. Assumed "gmail merges doubles", is the header information, the bodies text, including the footer and the changed subject line merged or is the received email with equal thread information just eliminated? It doesn't sound like a smart feature, it does sound like a bug or a feature _against_ mailing lists. A user has got the choice to turn it off or on, to receive mails sent to a mailman mailing list by her/him. So the gmail feature is useless for the user. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
