Milter-greylist runs as smmsp and it requires access to /var/milter-greylist. The installation process does not give the correct permissions to /var/milter-greylist, and the milter does not start. To fix, change the ownership on this directory: chown smmsp /var/milter-greylist I’ve installed milter-greylist on Red Hat servers a couple of times and was tripped up by an unmentioned installation error.
