Onboarding, health checks and upgrades by the Stalwart engineers.
Support answers questions and fixes defects. Professional services cover the hands-on work around a deployment: installing and tuning a new one, reviewing an existing one, carrying it through a major upgrade, or building a feature it needs. Every engagement is a fixed-scope project with a written deliverable, carried out by Stalwart Labs engineers.
A new deployment installed, configured and tuned.
Onboarding takes a new deployment from empty servers to a tuned, documented service. It covers the decisions that are hardest to change later, such as storage backends and directory integration, as well as the tuning that usually comes only after weeks in production. Onboarding covers deployments of up to three nodes; larger clusters are scoped individually.
- Installation of Stalwart on your infrastructure, on up to three nodes.
- Choice and set-up of the storage backends for your size and availability needs.
- Domains, DNS records, DKIM, SPF, DMARC, MTA-STS and TLS certificates.
- Integration with your directory (LDAP or SQL) or identity provider (OpenID Connect).
- Spam filter tuning for your mail flow.
- Performance and resource tuning (caches, limits and queues).
- Backup set-up, with a test restore.
- Deliverable: a handover document describing the deployment and how to operate it.
An expert review of an existing deployment.
Deployments drift: settings that were right at installation stop fitting as the number of users grows, and new releases add options that are never switched on. A health check is a review of a running deployment by a Stalwart Labs engineer, with written findings and recommendations. It is advisory: the recommendations are yours to apply, or can be applied as a separate engagement.
- Configuration review against current recommendations.
- Security review, covering authentication, encryption, access control and exposure.
- Deliverability review, covering DNS records, authentication, reputation and blocklists.
- Performance and capacity review of servers, storage and queues.
- Backup and restore procedure review.
- Deliverable: a written report with findings ranked by priority and recommended actions.
Major-version upgrades planned and carried out with you.
Major upgrades can change configuration formats, storage layouts and defaults. Upgrade assistance plans the upgrade of a deployment, carries it out with your team and checks the result, with a rollback plan ready in case it is needed.
- Upgrade path assessment for your current version and configuration.
- Compatibility review of integrations, directories, storage backends and clients.
- A written upgrade and rollback plan.
- Execution of the upgrade with your team, in a window you choose.
- Post-upgrade validation of mail flow, client access and integrations.
Help through national approval of lawful interception.
Operators subject to interception obligations must document their implementation, test it with the authorities and, in some countries, obtain formal approval before the obligation takes effect. Stalwart Labs assists operators using the Lawful Interception add-on through that process.
- Documentation of the Stalwart interception implementation for the regulator.
- Integration tests with the authority's mediation or recording equipment, including the SINA Box link in Germany.
- Liaison during national approval, for example the Bundesnetzagentur Nachweis in Germany.
- Day-to-day operation (receiving orders and delivering to the authorities) remains with the operator or a trusted third party.
Features on the roadmap, delivered sooner.
When a feature you need is on the roadmap but not yet scheduled, or is not on it at all, you can fund its development. Stalwart Labs agrees the scope and a fixed price with you, builds the feature as part of the product and maintains it from then on.
- Fixed scope and fixed price, agreed before work starts.
- Built and maintained as part of Stalwart, not as a custom fork.
- The result lands in the Community or the Enterprise edition.
Migration from other mail servers.
Moving mailboxes, calendars and contacts from another mail server is offered as a separate service, launching in 2027. The Migration page describes the source systems, process and cutover options.
From request to handover.
-
Request. Tell us about your deployment and what you need, through the licensing portal or the contact form.
-
Scoping. An engineer confirms the scope, the prerequisites (such as access and the information needed) and the schedule.
-
Quote. You receive a fixed quote and a pro-forma invoice.
-
Delivery. The work is carried out on the agreed schedule, with your team involved where needed.
-
Handover. The engagement closes with its written deliverable and a review of the results with your team.
Professional services FAQ.
-
Are professional services included in the SLA plans?
No. SLA plans cover support: answering questions and fixing defects within a guaranteed response time. Professional services are separate, one-off engagements, and can be bought with or without an SLA plan.
-
Who can buy professional services?
Professional services are available to Enterprise customers. Lawful-interception compliance assistance is available for Stalwart On-Premise only, like the Lawful Interception add-on.
-
How are services priced?
Each service has a fixed price for its standard scope, and larger deployments are quoted individually. A quote and a pro-forma invoice can be obtained from the licensing portal.
