Problem:
IMAP clients always show English folder names (Inbox, Sent, Drafts, Trash), while Roundcube displays them in the user’s language (e.g. German: Posteingang, Gesendet, Entwürfe, Papierkorb). This mismatch confuses customers.

Request:
Add a centralized option in Plesk to define IMAP default folder names based on server or mailbox language.

Apply correct IMAP SPECIAL-USE flags.

Allow automatic localization (e.g. German folder names) without manual Dovecot configuration.

Benefit:
Consistent folder names across Webmail and IMAP clients, less confusion and support effort.
