Users of #GNOME#Evolution mail client: in #Debian13#Trixie, the Message-ID search (via command line) is broken. 😔
It got fixed already (see https://gitlab.gnome.org/GNOME/evolution/-/issues/3079) but the fix version 3.57.1+ is too new in comparison to the Debian version 3.56.1-1.
There is a workaround to do a manual search within the UI:
Search → Advanced Search: https://gnome.pages.gitlab.gnome.org/evolution/help/mail-searching.html
"Add Condition" → switch from "Sender" to "Free Form Expression"
mid:""
It will get fixed in Debian in four years. 🙄
HTH
