2025: Red OS Compatibility

The joint work of the DeepMail mail client and the operating system Red OS is confirmed by the corresponding certificate of compatibility and the test protocol carried out according to the methods of the developer "Iridium," which announced this on April 3, 2025.

Server email DeepMail has demonstrated stable and correct operation based on the company's domestic operating system. " Red Soft Now organizations interested in switching to the domestic solution stack can consider DeepMail based on RED OS as an analogue of foreign products for working with e-mail.

DeepMail is an email server and cross-platform email client that fully matches the functionality of MS Outlook and MS Exchange and can be installed on stationary and mobile devices that support popular operating systems.

The testing methodology included checking the server for authorization, account configuration, administration, domain controller connectivity, mail domains, and fault tolerance tests. After that, the client was tested: login and registration, sending incoming and receiving outgoing letters, working with local contacts, customizing the appearance and style, setting up rules, hotkeys, templates and the necessary protocols. As a result, the correct operation of the solution and the main RED OS distributions was confirmed when executing various commands, as well as support for LDAP, SMTP, IMAP, calDav and cardDav protocols was confirmed.

Technical piloting has shown the stable operation of the DeepMail mail client on devices with a pre-installed RED OS operating system and can be used by a wide range of customers solving business problems as part of import substitution. The received compatibility certificate gives users of Russian operating systems another workable alternative, - commented Yulia Denisenko, General Director of Iridium.

The RED SOFTWARE ecosystem includes products designed for import substitution of solutions at all levels of the IT infrastructure. RED OS acts as the basis - an operating system for servers and workstations. Compatibility with DeepMail opens up new opportunities for our active users who are thinking about switching from foreign mail solutions to Russian products, - commented Rustam Rustamov, Deputy General Director of RED SOFT.
