Control high-volume SMTP delivery on your own servers or cloud VMs.

Deploy PowerMTA when you want dedicated control over your sending IPs, retry queues, and per-domain rate limits without building queue management from scratch. Isolate transactional, marketing, and multi-tenant traffic onto separate virtual MTAs, respond automatically to ISP throttling, and scale throughput on a compact hardware footprint.

Granular SMTP control on a compact server footprint.

Run PowerMTA on bare metal or cloud instances to manage per-ISP connection limits, retry schedules, and bounce classification from one configuration.

Backoff and throttling rules

Detect when a receiving provider defers connections or returns rate-limit errors, then automatically throttle throughput and pause retries before a temporary block turns into a blocklist listing.

Per-domain queue visibility

Inspect active queues, connection counts, and retry backlogs by destination domain in real time so your team can spot delivery bottlenecks as they happen.

Detailed bounce and delivery accounting

Classify hard bounces, soft deferrals, spam blocks, and policy rejections across dozens of bounce categories to feed clean suppression updates back to your application.

Live SMTP response tuning

Adjust concurrent connections, messages per connection, and retry intervals per destination ISP based on live SMTP responses rather than static guesswork.

Predictable volume-based licensing

Size your PowerMTA license around your sending volume and scale capacity for seasonal peaks, failover nodes, or staging environments.

On-premises or public cloud deployment

Run the same lightweight MTA binary on your own Linux hardware or on AWS, GCP, or Azure instances while keeping full ownership of your IP addresses and credentials.

Isolate sending streams with virtual MTAs.

A noisy marketing blast or a single misbehaving tenant should not delay password resets and order receipts. PowerMTA lets you partition a single server instance into independent virtual MTAs, each with its own outbound IP pool, DKIM signing keys, rate limits, and retry queues. Transactional mail, promotional broadcasts, and individual customer streams stay separated at the transport layer while your ops team manages one deployment.

Shift traffic to hosted email at your own pace.

Operating PowerMTA does not lock you into managing every server forever. You can configure PowerMTA to relay a percentage of your traffic to the hosted Bird Email API, compare inbox placement and operational overhead on a live slice of mail, and shift additional streams when your team is ready. Keep strict on-premises workloads on your own hosts while offloading cloud-friendly traffic without rewriting your application's sending code.

Domande su PowerMTA

Posso usare PowerMTA e la piattaforma hosted insieme? Chi controlla gli IP di invio?
Sì. PowerMTA può inoltrare parte del traffico alla Bird Email API hosted continuando a consegnare il resto direttamente dai tuoi server — il modo più semplice per provare la piattaforma hosted o migrare gradualmente senza spostare tutto in una volta. PowerMTA stesso gira su infrastruttura di tua proprietà, quindi quegli IP restano sotto la tua gestione. Il traffico che inoltri alla piattaforma hosted può utilizzare i nostri IP oppure i tuoi IP dedicati, mentre tutto il resto rimane interamente sotto il tuo controllo.
Cosa sono gli MTA virtuali?
I Virtual MTA permettono di eseguire diversi flussi di invio indipendenti all'interno di una singola istanza PowerMTA, ciascuno con i propri IP, reputazione e limiti. Usali per gestire separatamente posta transazionale, posta marketing o clienti diversi. Domini condivisi e policy dei provider destinatari possono comunque influire sulla consegna tra i flussi.
