The assembly is a full-fledged corporate mail server. You will be able to add users on your own, set up additional mail domains, manage users and settings through a convenient web interface. Also, the mail server has a configured web interface for working with mail.
All settings have already been made, you get a ready-made working mail server. You will need to specify a domain and set up DNS records. If necessary, you can install additional packages and configure services as you need. All applications installed on the server are free and distributed freely on the Internet, which is an advantage - you pay only for the resources of the server itself.

- No restrictions on the number of mailboxes, domains
- Ability to fine-tune services (all settings are available)
