Hello, I have a question regarding IMF 2 : I can apply IMF manually by checking “Apply Intelligent Message Filter” (on Default SMTP Virtual Server Properties -> Advanced -> Edit), but how can I do that using a script? Currently I’m using the following script to modify the Gateway Blocking SCL Rating: … Set obj = GetObject("LDAP://" & sDN) obj.msExchUceBlockThreshold = 5 … Which works fine, but I can’t find the right parameter to modify the “Apply Intelligent Message Filter” setting - by the way, msExchUceEnabled doesn’t do the job. Thanks for your help in advance. Robert
