Proxmox Mail Gateway

What Proxmox Mail Gateway is

Proxmox Mail Gateway is an open-source email gateway for Linux and the web, deployed in a gateway role with outbound filtering. The product has four paid annual plans, and every tier lists the complete feature set plus stable, secure updates. Community costs €190 a year and provides community support. Basic costs €540 a year with five support tickets and Customer Portal support. Standard costs €1,260 a year with 15 tickets, a four-hour response time, and remote support. Premium costs €1,900 a year with unlimited tickets, a two-hour response time, and remote support. The tiers therefore differ by support allocation and response commitments rather than the stated feature set. No free plan is listed. Proxmox was founded in 2005 and is headquartered in Vienna, Austria.
