Awesome! Thanks!
I need to understand the grey/whitelist bit... before proceeding though...
Not yet sure what's all involved for configuring it properly,
but thanks, for your contribution!

Looks like I am running to a couple of problems:
1) Starting greylist-milter daemon:
a) # service milter-greylist restart
Stopping Milter-Greylist: [ OK ]
Starting Milter-Greylist: /usr/sbin/milter-greylist: Symbol `GeoIP_\
country_code' has different size in shared object, consider
re-linking [ OK ]
b) In /var.logs/maillog:
[...] cannot read dumpfile
"/var/lib/milter-greylist/db/greylist.db"
2) Restarting Sendmail (SELinux issue?)
Starting sendmail: 451 4.0.0 /etc/mail/sendmail.cf: line 1833: \
Xgreylist: local socket name
/var/run/milter-greylist/milter-greylist.sock \
unsafe: Permission denied
