Dear Sir,
The forwarded mail is already detected as a spam and marked { Spam ?} tag in the subject line. In the initial setup it is set to "Tag and Deliver" which will cause the mails to be tagged as {Spam?} in the subject line and will be delivered to the end user.
If you do not want to received spam tag mails also then you can set quarantine action for spam mails from ECM Dashboard
For more details please go through the following steps
How to select Quarantine action on Spam mails and use of quarantine option

Then go to Administer -------> Personal Details -------> Edit

Quarantine Action click on Modify
It will take approximate 30-60 minutes to update changes on our all servers
Note: Quarantine action will cause the spam detected mails to
get quarantine on our servers only and will not be reach to intended
