We are running SBS 2011 and are on Exchange 2010 SP3. There are some internal emails going into the Junk folder in users Outlook 2010. They show an SCL number of 9. The first is .wav files being forwarded from our Mitel 5000 phone system which is set up to relay off the Exchange server. The second, also a relay, is from a program on our HyperV 2008 R2 standalone box. Both are using internal email addresses, so they should be safe! We've done the usual - not Junk in Outlook, but because of the SCL rating, that doesn't apply. So, how does one change an SCL in Exchange when the email address is already in the accounts list?
