Permissions should be 750 as the clamav user is a member of the amavis 
group and needs group access.

That will likely cause other problems. The clamav user just needs to be 
a member of the amavis group.

As you have seen there are differences between the packages. This makes 
the CentOS documentation worthless to you as you are not using the same 
versions used in the documentation.

You should take this thread, and your issue, to the EPEL list as it 
really has nothing to do with CentOS.
