Spam issue in using single Exchange Server 2007, Forefront Security for Exc. Srv and Outlook 2007

Hi All,

I've implemented these scenario:

Exchange Server 2007 SP1 (HT, CAS and MBX server)
connected to a Solaris smarthost for a proxy

Forefront Security for Microsoft Exchange Server 2007 SP1 + Regular updates

Outlook 2007 SP1 + regular updates (including junk mail filter update)

but still I'm getting spam into inbox and for some user the junk mail is not even goes into the jink mail folder ?

I also notice that I'm getting spam from my own domain but with the random string in front of the sender (eg. blabla@yourdomain.com where yourdomain.com is your AD domain).

is there any way to minimize the spam in this cenario ?

thanks.

Gordon,
I've created SPF for this cause and for the smtp authentication (Receive connector authentication)
  1. Transport Layer Security
  2. Basic Authentication
  3. Exchange Server authentication
  4. Integrated Windows authentication
  5. Externally Secured (for example, with IPsec).
all of them left unchecked. Which one should i check for a Solaris proxy box then ?

and for the next tab,

I also noticed that the Permission Groups "Specify who is allowed to connect to this Receive connector" are all checked.
