I'm a bit confused since the subject is not changed, but the body is marked as spam. And it was still been delivered.
Then, I just found the following:
"To simply have the server DELETE and NOT deliver emails that are tagged as spam by SpamAssassin, click here now."
I clicked in the option, which seems to add an extra scripting that might delete the email at once.
Spam (tons) is been delivered to my personal email that I created under my domain.
Thank you all,
