PIX 506 - Adding rule to disallow SMTP?

I have been trying to figure out how to add a rule to my PIX to disallow all SMTP traffic except it it comes from my internal mail server (192.168.1.1).  I can't seem to get it working correctly through the PDM, due to wrong order/rules/whatever I can't seem figure out.  Here is my current access list, with everything working great, except I want to dissallow all SMTP traffic except from 192.168.1.1.

Result of firewall command: "show config"
