I have identified a second, similar problem. Some MUA insert(s|ed) the From: address into the References field. For an example see id:[email protected] https://www.mail-archive.com/[email protected]/msg24266.html This seems to be another throwback to rfc822 I don't know how notmuch can detect this once it those references propagate to replies. - we could merge threads only based on messages known to exist (ignoring ghost messages), but presumably there's a reason we invented ghost messages - we could, at some point in future support blacklisting references (using message properties). _______________________________________________ notmuch mailing list [email protected] https://notmuchmail.org/mailman/listinfo/notmuch
