Mail Infrastructure / Deliverability
4SO Mail Gateway
A Linux/VM-first platform for outbound delivery, inbound protection, routing, reputation and mail lifecycle operations.
The problem
Mail sits at the intersection of protocol, reputation, security and operations; a real mail product must own lifecycle and observability beyond installing an MTA.
Leadership & architecture
Kept the data plane on hosts/VMs, avoided unnecessary Kubernetes complexity and designed the product independently from hosting panels.
Value created
Packages deliverability, routing, protection and lifecycle into a manageable capability instead of disconnected configurations.
Truth boundary
AI is an operations aid, not a delivery-path dependency; physical certification remains separate from source readiness.
