MailNexus is a developer-focused tool that turns the painful, error-prone process of setting up a self-hosted SMTP stack — Postfix, OpenDKIM, SPF, DMARC, TLS — into a repeatable, wizard-driven workflow.
Our mission
We believe owning your sending infrastructure should not require a sysadmin. MailNexus generates the exact install script, DNS records, and SMTP credentials for your VPS, then walks you through verifying everything works.
What MailNexus is not
- An email service provider — we do not relay your email.
- A bulk-mail tool for cold outreach or spam.
- A managed service for your VPS — you remain the operator.
Pricing model
Pay only for what you use. One credit = one fully configured server. No subscriptions, no lock-in, and credits do not expire.
