Not ready for a full setup yet? Try mox in less than a minute: download and run "mox localserve". It serves a local-only SMTP/IMAP/ Webmail/etc for testing and development. No setup required. Background # Work on mox started in 2021. Admins were migrating their emails to just a few cloud/hosting providers. In part because running and maintaining email software had become more complicated over time: additional email protocols required yet another component in the software stack. Combining all these components into a working email server had become too troublesome over time. These components were also often written in C, a programming language where a small mistake typically has large consequences. Mox is a modern email server that implements all modern email protocols in a single easy to use and maintain application. Sponsors # Mox development is sponsored from August 2023 to August 2024 through NLnet/EU's NGI0 Entrust, see https://nlnet.nl/project/Mox/. feedback? 2025-01-20, commit 315f10d
