I am using the files poppassd.server and poppassd.socket as distributed, I have also tried to comment out all of the "hardening" stuff but no change.

if i run /usr/local/sbin/poppassd from the CLI it immediately responds with "200 poppassd"

I do have selinux disabled

the included systemd files just do not work at least on rhel/centos 8

better install xinetd and use the classic way.

cat /etc/xinetd.d/poppassd

default: off
