Looking for examples I could share, I searched for Spam Quarantaine notifications **using notmuch-mutt**     (The binding I use for the search in mutt is the following (copied from https://notmuchmail.org/notmuch-mutt/) macro index L "unset wait_keyread -p 'notmuch query: ' x; echo \$x >~/.cache/mutt_terms~i \"\`notmuch search --output=messages \$(cat ~/.cache/mutt_terms) | head -n 600 | perl -le '@a=<>;chomp@a;s/\^id:// for@a;$,=\"|\";print@a'\`\"" "show only messages matching a notmuch pattern") The notmuch search did not find any message! This same macro executed with "Spam" as argument finds a few messages containing the word spam but none having it in the from field Repeating the searches with plain notmuch from the command line found all of the messages! So it is probable that my mutt configuration somehow has a problem. Once this is fixed I'll search again for thoses cases where some messages are found but not all of them. Any tip appreciated of course but I guess this is probably no longer the right place to ask!
