About this Gig
Still running PowerMTA or GreenArrow but need a more programmable, observable and policy-aware delivery platform?
I migrate production MTA environments to KumoMTA through a staged engineering processnot a blind reinstall. I map routing, pools, sending identity and provider policies, then rebuild them as a controlled KumoMTA architecture.
Your migration can include:
- Architecture and migration-risk assessment
- VMTA, pool, routing and policy translation
- KumoMTA egress design, Lua logic and TSA automation
- Provider/MX-aware shaping, retries and backoff
- SPF, DKIM, DMARC, PTR/rDNS, HELO/EHLO and TLS review
- Bounce, complaint, FBL and suppression workflows
- MailWizz/application integration and monitoring
- Controlled cutover, rollback and handover
When existing sending IPs are retained, I keep PTR/rDNS and HELO/EHLO stable where appropriate to reduce reputation disruption.
Preserve reputation. Translate policy. Modernize operations.
Migration is engineered to protect continuity, while reputation and inbox placement still depend on sender history, data quality and provider decisions.

FAQ
Is this just a KumoMTA installation or a full MTA migration?
This is a staged MTA migration and modernization service. I assess your PowerMTA or GreenArrow environment, map routing and policies, build KumoMTA, validate the new path, and plan a controlled cutover with rollback.
Why should I consider moving from PowerMTA or GreenArrow to KumoMTA?
Migration can make sense when you need deeper programmability, Lua-based policy control, TSA automation, observability, or a different infrastructure model. I assess technical fit first rather than recommending KumoMTA blindly.
Can my existing sending IPs, PTR/rDNS and reputation stay stable during migration?
Where technically appropriate, existing sending IPs, PTR/rDNS, HELO/EHLO and sending identities can remain stable to reduce unnecessary reputation disruption. Reputation itself still depends on history, data quality and provider decisions.
Can you translate my VMTAs, pools, routing and provider policies into KumoMTA?
Yes. I map the operational intent behind VMTAs, pools, routes and shaping rules, then translate it into KumoMTA egress sources, pools, Lua logic and TSA policies. I do not blindly copy configuration syntax.
Will a PowerMTA or GreenArrow migration require downtime?
Not necessarily. For production systems, I prefer discovery, parallel build, validation, controlled traffic movement and rollback planning. Actual downtime depends on your topology, integrations, DNS changes and change window.
Can you migrate other SMTP or MTA environments to KumoMTA?
Yes. PowerMTA and GreenArrow are the primary targets, but I can assess other commercial or custom SMTP/MTA environments for KumoMTA migration when their architecture and workflows can be mapped safely.
Can MailWizz, webhooks, bounces, complaints and suppression continue after migration?
Yes, where compatible. I can preserve or rebuild MailWizz/application integration, bounce handling, complaint/FBL workflows, suppression logic and webhooks within the agreed scope, then validate them before cutover.
How does KumoMTA support provider-aware delivery after migration?
KumoMTA supports programmable Lua policies, Traffic Shaping Automation and provider/MX-aware controls. During migration, I translate required rate, connection, retry, backoff and routing behavior into the new operating model.
Which package should I choose for my MTA migration?
Basic is for migration readiness and planning. Standard covers a staged production migration. Premium is for broader MTA modernization with advanced Lua/TSA, routing, observability, workflow integration, rollback planning and handover.
Can you guarantee zero downtime, reputation preservation or inbox placement?
No engineer can guarantee mailbox-provider outcomes. I design for continuity, validation and rollback, while reputation and inbox placement also depend on sending history, recipient quality, complaints, content and provider decisions.
