Does roundcube receives mail automatically without login

By default, Roundcube does not automatically receive mail without a login. Roundcube is a web-based email client that requires a user to log in to access their email account.

However, there are a few scenarios where Roundcube can receive mail without a login:

1. IMAP/POP3 polling: Roundcube can be configured to periodically poll the email server for new mail using IMAP or POP3 protocols. This allows Roundcube to retrieve new mail without requiring a user to log in. To enable this feature, you need to configure the imap_poll_interval and pop3_poll_interval settings in the Roundcube configuration file (config.inc.php).
2. Cron job: You can set up a cron job to run a script that logs in to Roundcube using a specific user account and retrieves new mail. This approach requires some scripting knowledge and is not recommended for production environments.
3. Third-party plugins: There are some third-party plugins available for Roundcube that can automate the mail retrieval process, such as the "Auto-Login" plugin. These plugins can be installed and configured to retrieve new mail without requiring a user to log in.

To summarize, while Roundcube does not automatically receive mail without a login by default, there are some workarounds and configurations that can achieve this functionality. However, these approaches may require additional setup and configuration.
