Hello Kurt, Many thanks for your precious feedback below!
There is definitely no List-Post header in the emails sent by Discourse. It is actually a funny coincidence to receive your email on this today because it's precisely today that I started to change my mind on the idea that theproblem had to be fixed on Discourse's side. Precisely today I startedto think it might be at Mutt's level that theproblem could be fixed. Still, as I mentionned in another thread, I am subscribed to a list to which the posters send emails in Bcc and such emails are not recognized as lists by Mutt although, ijust checked, they do have the List-Post header. This also suggests to me that htere may be room for improvement in mutt itself, re its ways of identifiying that an emailcomes froma mailing list. Thanks again, Seb.
