I am using postini as my spam/virus vendor, my MX record points to them first than scan for spam/virus than deliver to my exchange 2003 server. I only allow a range of postini network to talk to my mail server. My firewall is Juniper SSG5. After doing some investigation, I find that my mail policy from postini to my exchange server is consuming most of my T1. I also experiment that when I disable this policy I get my T1 back. I spoke to my postini reseller and they said there is nothing they can do.
I am checking this website to see if anyone ran into this problem and found a fix?
thanks in advance
