Milter (milter-amavis): local socket name /var/run/clamav/clamav-milter-socket unsafe

I am getting this error since installing the latest patches for 15.6. socket permissions appear to be OK.

mail:/var/run/clamav # l
total 8
drwxr-xr-x 2 vscan vscan 120 Feb 23 13:16 ./
drwxr-xr-x 42 root root 1100 Feb 23 13:11 …/

-rw-r–r-- 1 root root 6 Feb 23 13:09 clamd.pid
srw-rw-rw- 1 vscan vscan 0 Feb 23 13:10 clamd.sock=

How to fix this?

There is not a milter-greylist package in leaps 15.6, or if there is, it is part of Amavis which is fully installed. I had already seen this post before. This is not a new install, I had this server running for years without this error until I patched it yesterday.
