After having a large number of virus-infected emails get through to users recently, I checked on the status of ClamAV's anti-virus signatures. It turned out that they were very old. So I ran freshclam manually (using 'clamav/bin/freshclam --config-file ~/conf/freshclam.conf').

That worked, but then I checked the Zimbra user's crontab, and it doesn't appear to call freshclam at all. So, how is freshclam supposed to be called on a regular basis? Is this something that I should be adding to the crontab manually?

I am using zcs-NETWORK-5.0.8_GA_2462.RHEL5.
