Title: Bcc emails still visible using Civicrm (Wordpress)
ThreadText: # Bcc emails still visible using Civicrm (Wordpress)
  
  (Asked by: username_0 on 2023-10-20)
  
  Email addresses sent using Bcc are visible to the recipients of the emails.
  
  Emails sent using the Bcc field of Thunderbird (actually, Cco in Spanish) work correctly and the standard "undisclosed-recipients" message appears. However, when I receive an email from admins using the Civicrm Bcc functionality, all email addresses that are in the Bcc field are visible in a new "Bcc" field in Thunderbird.
  
  The emails are sent and arrive correctly (all of them, i.e. the individual ones, the ones sent in public copy and the ones sent using blind copy or Bcc), but the latter should not show the email addresses at all to the recipients.
  
  Could it be an error caused by the fact that "Bcc" does not exist in Spanish but "Cco" is used in Spanish?
  
  Is this a bug or am I doing something wrong?
