Agreed, sometimes things get double posted. Currently I use the To/Cc to filter things, however that ends up sometimes with multiple e-mails in the same folder. I was planning on altering my filters on of these days to properly check both the To/Cc and also the start of the subject line for "[listname]" or "Re: [listname]" to filter things accurately. However, dropping listname would break that. Unless anyone wants to tell me of some secret header that mailman sends with it's list mails to help out?
X-BeenThere seems to contain the list email. However, the proper header is List-Id, standarised on some rfc.
