You could create a Roundcube plugin that would do that but that would only work for users that accessed there mail though Roundcube, if any of them accessed there mail directly it wouldn't function.

my roundcube server is configured with several imap servers, users access my roundcube, select their mail domain and enter their credentials, in this case that plugging would work, and if so, how to configure that pluggins
thanks for your help

I don't know of an existing plugin that would do what you want but it could be created. You can use the message_before_send hook to check the recipients  https://github.com/roundcube/roundcubemail/wiki/Plugin-Hooks#message_before_send and throw an error before the message is sent.
