You are right.

The former is unused:

   # ls -la /var/spool/amavisd/.spamassassin/
   total 8
   drwx------. 2 amavis amavis 4096 Dec 21 15:09 .
   drwxr-x---. 9 amavis amavis 4096 Dec 21 15:22 ..

If I remember right, I had created it experimentally at some point.
what is the homedir of "amavis" user? 

# cat /etc/passwd | grep amavis
amavis:x:988:983:User for amavis:/var/spool/amavisd:/bin/sh

/var/spool/amavisd is the standard home on CentOS packages.

Any ideas will be welcome!
