Free email users report automated filtering in Roundcube webmail

Users of Free email services in France have reported issues regarding automated email filtering within the Roundcube webmail interface. Some users observed that certain messages were being automatically diverted into folders such as SPAM, Commercial, or Social Networks without explicit user configuration.

Technical analysis revealed the presence of Sieve filters on the server side, specifically identifying headers like ‘X-ProXaD-SC’ containing states such as ‘state=SPAM’ or ‘state=HAM:CommercialEmail’. These filters appear to be managed by the service provider's infrastructure.

Guides for managing these accounts emphasize the importance of correct IMAP/POP server settings, TLS/SSL encryption, and the use of secure HTTPS sessions to ensure reliable access and security when using the Roundcube webmail interface.
