The settings will be different for everyone because what is spam to
some, is not spam to others.

 

Make your own determination by using an IMF manager and set IMF to
archive.  Then look at what it is classifying and what SCL it is
assigning.  Then you can make your determination on what to block and
what to allow to Outlook Junk mail for the user to decide.

Okay, has there been anyone who can say by setting the SCL to x numbers
its a hit and miss as suppose to missing or hitting all the time?

Higher SCL numbers are more likely to be spam.

So higher threshholds = more spam gets through, fewer false positives.

I am still not clear to the SCL settings. Which side of the scale does
more email get through IMF?

 

Thanks

You can't get there from here.

 

There is no way to keep messages from getting high SCL ratings.  If you
pemit SCL-based filtering, all mail coming into Exchange from SMTP
sources within your network will be subject to it just the same as mail
of external origin.  The only whitelisting provision for SCL ratings is
based on subject and/or body content.  AND THAT WHITELISTING FEATURE IS
BROKEN AND THERE IS NO HOTFIX.  (the whitelisting feature is explained
in the SP2 release notes).

 

The inability to whitelist at the SCL level based on IP is a major
omission in IMF, IMHO.  You might check with these guys to see if their
IMF tweaker works with IMF V2.

My current configuration for IMF is the following:

 

Under ESM -> Global Settings -> Message Delivery

 

1.      I have added the IP address of my Exchange/SMTP server under the
General TAB 
2.      Under IMF TAB Gateway is 4 with reject on, and Junk-Email is 2 
3.      Under Connection Filter TAB - Under Global Accept and Deny List
Configuration -> Under Accept are the IP address for ExchangeList,
ISAList, SBSList, etc. 
4.      Under SMTP server only the IMF filter is turned on everything is
turned off. 

 

I can't figure out for the life of me why IMF is still putting ISAList
emails in my Junk E-Mail folder after I added the IP to the Accept list
and restarted SMTP server??
