V11 policy detection or exception rules with Domain Pattern Matching fail to match on email domains. The domains are listed as:
test.com,symantec.com
We have etrack 2340221 created for issue, which was fixed in 11.6.
Workaround is to add @domain to beginning and detection will work again.
In the above example you would just change the following list to: @test.com,@symantec.com
