Exchange 2013 junk e-mail filter with safe senders list bug?


We've got unwanted experience with Exchange 2013 mailbox junk e-mail configuration. We've setup an account junk filter settings, that accept e-mails only from senders from safe senders list, with command:  

Set-MailboxJunkEmailConfiguration -Identity "Our Mailbox" -TrustedListsOnly $True -TrustedSendersAndDomains $ListOfEmails

Generally it works fine - if e-mail is sent by sender who is not on the list, that e-mail goes directly to junk e-mails folder. But there is one strange exception - if sender who is not on the list add e-mail address that is on the safe senders list as CC, that e-mail will be accepted and placed in Inbox folder.  

Is there any option or fix to change that behaviour?

Thanks for any help.
