I want to add a job to zimbra's cron.

1) I added a file in cron.me in location /opt/zimbra/zimbramon/crontabs which has the cron commands I want the zimbra user to run.

2) However, I don't see how to reload cron to read these scripts and assemble them into the crontab spool file for zimbra (/tmp/spool/cron/zimbra)

Should be an easy fix? Just can't seem to find the command.
