I basically have the same issue described solved in
I have a few additonal questions
I have a firewall that tags spam email with with the word "spam" and like the solution above I created a hub transport rule that tags the email with spam confidence level 9. Same as the solution in the link above but I am using Exchange 2010
Currently I have a rule set in everyones Outlook that was done with the GFI rule editor. I am moving from Exchange 2003 to 2010 so that does not apply anymore.
Because I dont want Outlook or Exchange doing any spam filtering I have setup a user GPO that blocks Outlook from doing spam checking.
Microsoft Outlook 2010/Outlook Options/Preferences/Junk E-mail
Junk E-mail protection level Enabled
Select level: No Protection
Do I need to enable junk email protection in Outlook 2010? Basically remove my GPO?
How do I prevent Exchange from doing spam filtering besides just filtering for this hub transport rule?
Thank you for your help
