How can I delete spam which IP addresses are blacklisted

[SvetMine]

Can someone explain me how I can delete the e-mails which are tagged and the message from details is:
from ip is in FortiGuard-AntiSpam ip blacklist.

I want to delete automatically all these mails and not to come to my Exchange server 

Thank you in advance

You need to set an action in the profile which is triggering this detection.  Each detection method in the AS Profile can have a different Action set or can use the --default-- which is defined at the top of the Profile.  Change the Action for the FortiGuard group of detection methods to e.g. Personal Quarantine.
