Milter-greylist

While this may have been frustrating and/or amusing, I have installed 
milter-greylist on a CentOS version 4.5, 4.7, and 5.2 which should be 
similar to installing on Fedora and it is a pretty painless thing.  I 
am sure part of it may depend on the add-ins you want compiled in, but 
the rpmbuild command in the readme did most of the work for me.  

The biggest thing it didn't do was change the ownership of 
the /var/milter-greylist folder to be owned by smmsp.
