MTA-Hub interface

Your whole infrastructure —
in one panel.

Watch sending, server health and problems from a single window. Go from the big picture down to a specific node, queue or bounce.

How it works

From a task to professional infrastructure

You set the parameters. The Hub helps you get from sizing to day-to-day control.

  1. Planning: sizing nodes, IP addresses and domains for your sending volume

    Planning

  2. MTA installation: PowerMTA or MailerQ on your servers

    MTA installation

  3. IP warm-up: gradually ramping up sending volume

    Warm-up

  4. SMTP export: connecting servers to your email marketing platform

  5. Control: monitoring delivery, queues and bounces

    Control

Behind every step is work the Hub takes off your hands: it sizes the server set for the volume you need, installs PowerMTA or MailerQ, configures SPF, DKIM, DMARC and reverse DNS, runs the warm-up on schedule and adjusts the pace to how mailbox providers respond. Ready SMTP connections go into your email platform — Protosender, Mumara, Interspire or MailWizz — while queues, bounces and the deliverability of every node stay visible in one panel.

Your scenario

Infrastructure from scratch
or scaling up what you have

Start with a step-by-step setup, or bring the servers you already run under one panel.

First launch: from a task to a ready SMTP server

First launch

From a task to ready SMTP servers

  • Size nodes, IPs and domains for your volume.
  • Install the MTA and set up mail DNS records.
  • Start the warm-up with the sending pace under control.

Running infrastructure: a fleet of SMTP servers managed by one Hub

Running infrastructure

Manage your SMTP fleet in one place

  • Bring servers and domains into one workspace.
  • Keep configurations, queues and bounce reasons in check.
  • Add nodes as your workload grows.

FAQ

Questions before you start

About the product, installation and getting started.

How is MTA-Hub different from an email marketing platform?

The Hub installs and configures MTAs, manages your SMTP infrastructure and exports ready SMTP connections. Campaigns and messages stay in your email platform.

Where is MTA-Hub installed?

It is self-hosted software: the panel is installed on your own server. Access credentials, keys and databases stay with you.

Which MTAs are supported?

PowerMTA and MailerQ. A PowerMTA license is purchased separately from the vendor.

Can I connect an existing infrastructure?

Yes. The Hub adds your servers as nodes and shows their health, configurations and the infrastructure diagram. Each server is checked before any settings are applied.

Is the Hub suitable for a first launch?

Yes. The Specification helps you size resources, then the Hub installs the MTA, sets up domains and helps you run the warm-up to plan.

Where can I see the interface?

The Interface section on this page shows screenshots of the MTA-Hub panel, and every screen is covered in detail under Modules.

How do I choose a license?

Every plan includes all modules — plans differ by term, support and updates. See the Pricing page for details; a PowerMTA license is purchased separately.

Work out what your task needs: nodes, addresses, domains and a cost estimate. The estimate commits you to nothing.
