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.

# 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!
