Hello, The mail by Alexander Dahl that is (currently) the first hit on https://lore.ptxdist.org/ptxdist/?q=ptxd_make_world_compile_commands_filter results in a 404 when I follow the link. The original mail has Message-ID: and the corresponding link is: https://lore.ptxdist.org/ptxdist/Y+07h0l%2FzJJAgs9s@falbala.internal.home.lespocky.de/ I noticed this on public-inbox 1.8.0-1~bpo11+1 from Debian, upgrading to 1.9.0-1~bpo11+1 didn't help. Other mails with / in Message-Id are not accessible either, I tested with: YyHu/412LT8uQTy1@lenoch Y0/5xdFZO3u0952+@lenoch I also wonder why these mails yield the webserver's 404 page and not the one provided by the public-inbox cgi?! Is this a problem in public-inbox, or is the apache configuration somehow borked? Any hints welcome.
