    • makeNotificationSender

      public static String makeNotificationSender(String from)
      This function will change email address in 'from' field by address of mail service which is configured as system property : gatein.email.smtp.from or mail.from.
      That ensures that 'emailAddress' part of 'from' field in a message object is always the same identity with authentication of smtp configuration.
      It's because of 2 reasons:
      • we don't want notification message to show email address of user as sender. Instead, we use mail service of kernel.
      • Almost authenticated smtp systems do not allow to separate email address in from field of message from smtp authentication (for now, GMX, MS exchange deny, Gmail efforts to modify the such value)

      from -
      Returns:
      null if can not find suitable sender.
