## The Hook

Mailpit catches SMTP in Docker and CI so you can read the email without sending it.

## What's Good

MIT. Single Go binary, MailHog-compatible ports (1025/8025), web UI, REST API, search, TLS. Drop-in image swap from abandoned MailHog.

## The Catch

Sink only — not delivery. Not Resend SaaS, not Postal/Listmonk outbound. Do not point production MX here. Distinct from Resend/Postal/Listmonk.

## Verdict

MIT MailHog successor for local/CI. Free forever; not a mailer.
