Limit to Postini IP Range in Plesk

I'm trying to limit incoming mail to only the IP range Postini provided me.  How can I make this work in Plesk's control panel where it doesn't seem to accommodate ranges?  Thx!

IP Range
74.125.148.0 - 74.125.151.255

CIDR Range
74.125.148.0/22

IP/Subnet Mask Pair
74.125.148.0
mask 255.255.252.0

If you have ssh access to the server, login as root and type:

iptables -A INPUT -s 74.125.148.0/22 -p tcp --dport 25 -j ACCEPT
iptables -A INPUT -p tcp --dport 25 -j DROP

Any changes to the firewall module in the control panel or rebooting the server will drop these rules and will need to be re-entered.  If you let me know the version of linux you are using I can tell you how to save these indefinately.  Alternatively you can attempt to translate these in the firewall module, but I think this is your issue.
