Internal Spam

I have a MS Exchange 2003 environment ... For the SPAM filtering ( Going out / Coming In )  , we are using  Symantec MailSecurity ... and it does a good job so far... My problem now is , users are getting spams, which I believe , is originated from with in our LAN .... I checked the Syamantec MailSecurity Logs, and it hasn't come from Outside for sure ...

We have 1000s of PCs in our organization which are spread in so many different locations ... How can I block / identify the PC which sends these spam messages ...

Below you can see an example of the spam message I got ...

From : Angeline1984@ax.com

To: Myname@mydomain.com

I participate in competition of an hard erotic photo. Please vote me! You must see that!: http://jso-gf.mail15.su

How can I block these spams, it is making huge problems now, because these messages are being sent to Distribution Lists as well ...

Thanks in advance,
