Microsoft Internet Message Filter does not work
Posted on 2005-04-19
We have Small Business Server 2003 Premium and have downloaded and installed the IMF from Microsoft. It installed without any errors and the configuration tab regarding blocking e-mails according to SCLs, etc. shows up as well. I have also gone to the SMTP server section in Exchange and IMF is check marked to be active.
However as part of the installation instructions, you are supposed to be able to run an IMF performance counter to see the SCL ranges on incoming e-mail. Unfortunately the IMF performance counter does not exist on our server. I was told that you have to recieve an e-mail in order for the counter to be created. We have definitely received e-mail with one user getting about 300 junk e-mails a day.
I currently have the settings configured to reject e-mails with SCLs of 7 or higher and place all e-mails in the user's junk folder with an SCL of 4 or higher, but this doesn't do anything. The only note is that we are using SMTP to send out our e-mail and are using the POP3 connector to receive our e-mail. I am wondering if the POP3 connector ignores junk e-mail. Do we have to use SMTP to receive our e-mail for IMF to work? We do want to get our MX info changed so that our server will receive our e-mail instead of it going to our hosting provider. Any help would be appreciated. Thank you very much.
