docker-mailserver

docker-mailserver is a production-ready, full-stack mail server that runs inside a container. It brings SMTP and IMAP services, LDAP support, antispam protection, antivirus functionality, and other mail server features together in one environment. Configuration is handled entirely through files, and the server does not require an SQL database, avoiding separate database setup and management. It is intended for people and organizations that want to run a complete container-based email server and prefer file-based configuration. It can replace Gmail as the system used to provide email services. One important difference is that docker-mailserver is software for running and configuring a mail server rather than a paid email product: its operation is centered on a container and configuration files. This makes its setup model different from Gmail, even though it can serve as an alternative for email hosting.
