The open-source Amazon SES replacement
Nitrosend's mail delivery engine, open sourced. NitroMTA is a self-hosted engine that speaks the Amazon SES v2 API: keep your SES code, change the endpoint, and send from your own IPs and domains. New IPs warm up receiver by receiver, and nitromta doctor checks every DNS record a receiver looks at. In our published benchmark, on the same AWS bare-metal server with every message on disk before it was accepted, it sustained 3.16× KumoMTA's throughput and 4.11× Postfix's. Rust, Apache-2.0.
NitroMTA is an open-source mail delivery engine that replicates the Amazon SES v2 API, allowing users to self-host and send emails from their own IPs and domains. It offers superior throughput compared to KumoMTA and Postfix, with additional features for IP warming and DNS record verification.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
