Ok those links were helpful but I guess I'd like a little more hand holding if possible

Here's what I've got so far from the links:
clamav-x.xx.x
Ok to delete all but the one that "clamav" is linked to.
config.#####
Ok to delete all numbered config files; don't delete config.save (I didn't have this file, however, fwiw)
amavisd-new-x.x.x
jdkx.x.x_xx
Do not touch.
Since some things with multiple versions are OK to delete and others not, I would feel better if someone explicitly commented on the following components as to whether it's OK to delete all but the most recent version:
cyrus-sasl (cyrus-sasl-2.1.21.ZIMBRA; cyrus-sasl-2.1.22.3)
mysql (mysql-standard-5.0.33-pc-linux-gnu-i686-glibc23; mysql-standard-5.0.45-pc-linux-gnu-i686-glibc23)
snmp (net-snmp-5.4; net-snmp-5.4.1)
openldap (openldap-2.3.34; openldap-2.3.39.5z)
perdition (perdition-1.17; perdition-1.17.1; perdition-1.17.1.1z)
sleepycat (sleepycat-4.2.52.4; sleepycat-4.2.52.6)
Lastly, in the log folder there are zimbrastats.csv.####-##-## files dating back to my initial installation nearly a year ago. Is there any reason to keep these or are they safe to delete?
Thanks.
