Pourquoi c'est important
You spend days perfectly configuring your custom mail server, only to discover that major tech companies silently blackhole your outgoing messages because your virtual private server resides in an untrusted IP range. You need the privacy and control of hosting your own data, but you cannot afford the anxiety of wondering if your critical communications are actually reaching their destinations. Existing cloud relays are built for enterprise marketing blasts, lacking the simple reputation dashboards and developer-friendly onboarding that individual infrastructure enthusiasts require.
