I've done some further looking at this. This is *not* a ruby-talk problem in any way. Ruby-talk does behave a little differently than most other mailing lists, and part of it is what you illustrated in your message above ([ruby-talk:197553]). ruby-talk adds a few extra headers that most mailing lists do not. This gives Gmail the impression that it is a wholly separate message and therefore it doesn't suppress it (or better, suppress your *sent* copy) on receipt. This is something that the Gmail team needs to fix; they know the message-id that they used when sending the message; they should know that a message that matches in every way except headers should *also* be the same and therefore should suppress your sent message in favour of the (marked up) message from the mailing list. But I have *always* had both my sent copy and my received copy regardless of the MUA that I've used. It's just that most MUAs don't copy the sent message to the originating folder. -austin -- Austin Ziegler * halostatue@gmail.com * http://www.halostatue.ca/ * austin@halostatue.ca * http://www.halostatue.ca/feed/ * austin@zieglers.ca
