Proxmox with Mail Scanner

[kotakomputer]

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?

That will be a great idea

Well you could always pay for the proxmox mail system.

I personally have a Ubuntu server which has postfix installed with all the anti spam turned on, gray list, rbl, spf, antivirus. I’m using dovecoat for storage, imap and pop access, MySQL for user accounts and round cube for webmail.

For anti spam storage I’m using mailZu which allows users to see and manage their own spam folders if you want.

Letsencrypt is used to generate the ssl certs.

I send all logs to a gray log server for storage, debugging etc and use observium for SNMP monitoring and alerting.

There are lots of guides but it’s also not for the faint hearted.
