Proxmox Mail Gateway for Secure Email Traffic
Proxmox Mail Gateway protects email traffic as a gateway in front of mail servers and groupware systems. It filters spam, malware and unwanted content and supports policy and quarantine processes.
PMG is a mail security gateway, not a complete security platform. It complements identity, endpoint, SIEM and collaboration security controls but does not replace them.
Proxmox Mail Gateway is an email security component for organizations with existing mail and groupware infrastructure.

Role in the security architecture
ForgeOne assesses MX flows, existing mail servers, groupware, quarantine workflows, TLS, DNS, monitoring and responsibilities before PMG is placed in production.
PMG is especially useful when email security should be transparent, self-operated and integrated into existing operations.

Mail security only works with clear processes for policies, monitoring and escalation.
Mail Flows & DNS
Validate MX, TLS, delivery, relay paths and failure scenarios.
Policies & Quarantine
Shape rules, releases and responsibilities so they work in daily operations.

Make delivery, filtering behavior and failure states visible.
