After getting all spamdyke working I enabled graylisting. My server started soft rejecting mail (mustafa actually informed me) and after checking logs I saw the error from spamdyke concerning graylisting:
Unable to create Dir /var/tmp/graylist.d/<domain>: permission denied.
the directory is set to root:root - I had to set it to 777 to get graylisting working and mail stopped being rejected.
I do not like this permission. What should the permission be? Under what user does spamdyke run?
Thank you
