Hi,
I can't enable smtp restriction.
When I try to enable from WHM, I got error.

I tried form terminal:
# /scripts/smtpmailgidonly on
But I got error too:

"SMTP Mail protection has been disabled. All users may make smtp connections.
There was a problem setting up iptables. You either have an older kernel or a broken iptables install, or ipt_owner could not be loaded."

Please help
