Ks! MailFlow Relay

The sane email forwarding engine

UX that just works

Transparent email forwarding without any unnecessary friction. By delegating everything related to management to the administrators regular users never even need to think about email.

Powerful when you need it

Optionally supports templating, fine-grained access controll and a lot of per-list customization options. Invisibly supporting your workflows without ever getting in the way.

Easy administration

At-a-glance overview of system state. Monitor bounces, Ratelimits, send-queue and everything else right from your browser.

Hot-reload configuration allows administrators to edit core settings on a running instance in production with zero downtime.

Multi-Provider support

MailFlow Relay can be deployed with whatever infrastructure you happen to have. Choose IMAP/SMTP if you already have a mailserver you want to enhance or set up AWS SES for a highly cost-effective pipeline.
