Self-hosted alternatives to Migadu

Migadu is a Swiss email hosting service for custom domains with unlimited addresses and standard IMAP, POP3 and SMTP access. One listed app does its main job and runs in your own Cloudflare account.

Each answer comes from the app’s README and source code, compared with the features Migadu describes on its own site.
