SMTP + IMAP + POP3 + Antispam + Antivirus
Web administration + Web email
...on your server in ~5 minutes
Fast deployment
You can have a full-featured mail server installed in a couple of minutes, mostly waiting for scripts to get the job done. The whole package is designed with reasonable defaults to get started quickly without knowing internals and without making decisions that can break the email system.
Data has its own volume
User data and configuration is strictly separated from binaries. The user database is stored in a SQLite database - in a file. Therefore, Poste.io can be fully used with external storage. Migration, backups or updates are therefore very easy and mostly consist of file manipulation.
Security
Poste.io has been built from the ground up with security in mind. Internet history is full of painful security incidents, so we traded old email client compatibility and insecure authentication methods for features that meet modern security requirements.
