My guess is that > notmuch has first seen the one in "sent", indexed that, and then seeing > the second one with the same messageId, skips it. notmuch doesn't "skip" anything -- it just knows that they are the same e-mail due to message-id matching. it actually indexes both texts. you can see this with: notmuch search --output=files id:$MESSAGEID > I'd prefer to have both, but if I have to pick one or the other, I'd > actually prefer to have the second one, as I'd then have > > [ pdp ] > > as the start of the subject header for ALL mails to that list, and as an > added bonus, afew (should?) then tag them with the list name making them > easily searchable. I'd recommend doing your tagging based on something other than a substring of the subject line -- wouldn't tagging based on the recipient of the message (To: or Cc:) be sufficient to group your mailing list messages under one heading, regardless of which variant notmuch chooses to prefer? i recognize this doesn't answer your proximal question -- and i'd love to hear if someone more knowledgable has a good answer for it. i'm just offering a workaround for what i think is your ultimate goal. all the best, --dkg _______________________________________________ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch
