First thing I would do is run yum update to bring the system patches up to speed.
You will have a kernel update if you haven't updated for 8 months, so you will
need a reboot.
Then you can use the following script to backup your mailscanner installation.
It is set up to run as root, and keep its stuff there.

#!/bin/bash
cp -a /etc/MailScanner /etc/MailScanner.$(date +%Y%m%d)
cp -a /usr/lib/MailScanner /usr/lib/MailScanner.$(date +%Y%m%d)
cp -a /usr/sbin/MailScanner /usr/sbin/MailScanner.$(date +%Y%m%d)
echo cp -a --remove-destination /etc/MailScanner.$(date +%Y%m%d)
/etc/MailScanner > /root/restorems-$(date +%Y%m%d).sh
echo cp -a --remove-destination /usr/lib/MailScanner.$(date +%Y%m%d)
/usr/lib/MailScanner >> /root/restorems-$(date +%Y%m%d).sh
echo cp -a --remove-destination /usr/sbin/MailScanner.$(date +%Y%m%d)
/usr/sbin/MailScanner>> /root/restorems-$(date +%Y%m%d).sh
chmod +x /root/restorems-$(date +%Y%m%d).sh
echo rm -fr /etc/MailScanner.$(date +%Y%m%d) > /root/delmsback-$(date +%Y%m%d).sh
echo rm -fr /usr/lib/MailScanner.$(date +%Y%m%d) >> /root/delmsback-$(date
+%Y%m%d).sh
echo rm -fr /usr/sbin/MailScanner.$(date +%Y%m%d) >> /root/delmsback-$(date
+%Y%m%d).sh
echo rm -fr /root/restorems-$(date +%Y%m%d).sh >> /root/delmsback-$(date
+%Y%m%d).sh
echo rm -fr /root/delmsback-$(date +%Y%m%d).sh >> /root/delmsback-$(date
+%Y%m%d).sh
chmod +x /root/delmsback-$(date +%Y%m%d).sh

This will back up your mailscanner setup with the current date. You can then
install the latest from Julian's install tarball and be sure you run the
update_mailscanner_conf and update_languages_conf scripts. Then you can
restart MailScanner.
If you need to restore a backup just run the restorems script with the date of
your backup.
I would also recommend updating spamassassin, but to get detailed help, we
need to know if you are running the spamassassin that came with CentOS, or if
you installed from Julian's clamav-spamassassin tarball.

MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
