Hello,
As mentioned in the title, I have 2 forests, with a single domain in each. Domain A runs Exchange 2010 Domain B runs Exchange 2016.
Scenario:
User in Domain A sends email to user in Domain B
Both users have the same SMTP domain namespace,
userindomainA@mydomain.com, userindomainB@mydomain.com
Email is tagged by Exchange 2016 servers with a SCL of 9, mail is subsequently routed to Users Junk Mail folder.
Scenario 2:
User in Domain B sends email to user in Domain A
Both users have the same SMTP domain namespace,
userindomainB@mydomain.com, userindomainA@mydomain.com
Email is tagged by Exchange 2010 servers with a SCL of -1, mail is subsequently routed to Users Inbox Folder.
In Domain A or Exchange 2010 environment I have a HubTransport Rule that says, any email sent from "mydomain.com" Set Spam Confidence Level to -1.
In Domain B or Exchange 2016 environment I have the same Hub Transport Rule that says, any email sent from mydomain.com set Spam Confidence Level to "0"... -1 deprecated in 2016.
Is this a bug? or am I missing something? Even tho my HT rule says mark with SCL of 0, it still has an SCL of 9 once it hits the users mailbox (junk folder).
