The Restena Foundation's configured and secure web interface, called Webmail, allows to send e-mails to a set of correspondents via groups (lists) of contacts. These groups offer the significant advantage of being able to send an e-mail to several people, a project team or a committee, without having to add each address individually to the To, Cc or Cci (Bcc) line.
The management of these groups is explained in a dedicated user manual, only available in French language.
