I've never heard of ProtectSystem before so I don't know how to disable it, but this might be your issue?

Thanks,

Is the s flag set on your /usr/local/sympa/bin/queue binary? And is it owned by the sympa user, I would assume?

Thanks,

Yes, I compared all permissions but I assume I miss something

I have installed a new debian trixie (13.3) server. The old one was debian bullseye (11.11). On the old one I used to install sympa from the sources. For a very long time I had no problems with sympa. So I installed the same version on the new server. In fact I used rsync to copy the installation, including the postfix configuration and then I compiled sympa on the new server with the same script. ./configure \     --prefix=/usr/local/sympa \     --without-smrshdir \     --with-lockdir=/var/lock/subsys \     --with-piddir=/run/sympa \     --with-initdir=/etc/init.d \     --with-unitsdir=/etc/systemd/system \     --with-aliases_file=/etc/postfix/sympa_aliases In postfix master.cf sympa   unix    -       n       n       -       -       pipe   flags=hqRu null_sender= user=sympa argv=/usr/local/sympa/bin/queue ${nexthop} sympabounce unix -      n       n       -       -       pipe   flags=hqRu null_sender= user=sympa argv=/usr/local/sympa/bin/bouncequeue ${nexthop} Sympa runs on the new server but there is something wrong. When I send a message to the list on the new server I see no error but the message is not delivered.

Please help
