Hi Omen, Short answer: it's already been fixed.
As you found, the old Sidebar wasn't counting "new" the same way as Mutt. If you have the time, please test the latest NeoMutt release: https://github.com/neomutt/neomutt If that doesn't help, please raise an issue and I'll fix it: https://github.com/neomutt/neomutt/issues > > I can verify the behavior does NOT happen with unpatched mutt, so > > something Debian is adding. Debian is still using quite an old version of the Sidebar. I'm working with them to get the latest Sidebar into mutt-patched. > + if (option(OPTSIDEBAR) && mailbox->msg_unread > 0) { > + mailbox->new = 1; > + return 1; > + } > + That code wasn't at fault, it was the counting which happened elsewhere. But, thanks for looking. It helped me zero-in on the problem. Rich / FlatCap
