After getting the unison sync working properly I attempted to setup

the job, it would stop the email. The entire cron line looks like
this: "*/5 * * * * root /usr/local/sbin/sync-qmail 2>&1 > /dev/null"
Was I misinformed or is CentOS 5 just different in how one stops the
emails from cron?
Thanks in advance for any suggestions!

Different than what/how?
Basically is the syntax I have above correct or should I be doing this a
different way? I noticed that there are other items in the crontab that
use the same ending (2>&1 > /dev/null) and I do not get emails from those.
Thanks,
Scott

That 'ending' is pretty conventional shell script coding. It says:
Redirect stderr (2>) to stdout (&1). Then redirect stdout (>, or 1>) to
/dev/null. Order is important here. If you redirect stdout before
stderr, then stderr will not come along with stdout because std has
already been redirected. You would need to ">/dev/null 2>/dev/null" to
get the same effect.
