The ebuild net-mail/popa3d-0.6.4.1-r2 creates a user popa3d, but when you start the daemon using the init script popa3d runs as root instead as user popa3d. Reproducible: Always Steps to Reproduce: 1. emerge popa3d 2. /etc/init.d/popa3d start 3. ps aux | grep popa3d
popa3d starts as root so that it can bind to port 110. Before authentication it chroots to /var/empty as the popa3d user.
