I have a mailserver with many mailboxes and different domains. Proxmox Mailgateway is sitting in front of this mailserver für incomming and outgoing mails.
Sometimes mailaccounts get hacked (or the user has an trojan) and then these accounts are sending out lots of spam mails.
Is it possible that Proxmox scans outgoing mails in the same way than incomming and then move spams also to quarantine instead of sending them out?
With this I try to avoid getting blacklisted. Of course I understand that several tests will not work (IP checks, DNSBL, ....)
Any help or tipps how to configure this would be highly appreciated and also your opinion if this is a bad idea.
