Proxmox with Mail Scanner

I need a mail scanner with anti-spam support installed to node. So, every emails send from any CT and VM will be scanned (w/o any changed to any VPS).
Spam email will be move to quarantine folder, and maybe a web ui so we can see the spam email details: contents, from which VPS, etc. Also, maybe automatically block the IP of infected VPS.

Any idea how to achieve this?
