Hi Emmanuel, I've just upgraded my workstation to Bookworm and the upgrade broke my (outgoing) mail setup where I'm using msmtp due to permission errors involving files owned by msmtp:msmtp. I see from your NEWS entry that SetGID support was removed because it conflicts with passwords retrieved through libsecret. Problem is in my deployment I'm not using passwords but rather TLS client certificates, which AFAICT the libsecret integration simply does not support so I cannot migrate my config to the non-setgid msmtp. I'd like to request a new package, say msmtp-sysconfig, that will make /usr/bin/msmtp setgid again on installation. I'd be happy to provide a patch if you agree this is a reasonable idea. Thanks, --Daniel
