Hello, I have a problem with filtering/tagging debbugs on gnu.org. Ricardo told me: > Notmuch should be able to filter by list. With mu4e I match for > “list:bug-guix.gnu.org”. All emails to the bug-* lists contain a header > for “List-Id”, which you may be able to match on. ( https://lists.gnu.org/archive/html/help-guix/2016-09/msg00082.html ) However reading `info notmuch-search-terms(7)' and trying to just search for list:bug-guix.gnu.org or without the list: prefix, not much turns up as result (only unrelated results). Is this not implemented in notmuch, and if it is not, how could it be achieved? Thanks.
