ForgeOne integrates Proxmox Mail Gateway as a mail security gateway for spam, malware, policy and quarantine processes.

## 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.

### Proxmox Mail Gateway

Mail security

### Gateway

Integrate in front of mail servers.

### Quarantine

Processes for review and controlled rollout.

### Policies

Operate rules transparently.

## 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.

## Operational focus areas

Mail security only works with clear processes for policies, monitoring and escalation.

### Mail Flows & DNS

Validate MX, TLS, delivery, relay paths and failure scenarios.
