This extension takes the content a field and uses this content (an e-mail address) when sending the form as CC address.

To do this MailPostProcessor.php of form is extended, see here: https://github.com/TYPO3-CMS/form/blob/master/Classes/PostProcess/MailPostProcessor.php

German:

Diese Erweiterung nimmt den Inhalt ein Feldes und nutz diesen Inhalt (eine E-Mail Adresse) beim Versenden des Formulars als CC Adresse. Damit erhält der Absender des Formulars eine Kopie.

method = post
prefix = tx_form
confirmation = 0
postProcessor {
    1 = mail
    1 {
        ccEmailField = email # uses field named "email"
        recipientEmail = [email protected]
        senderEmail = [email protected]
        subject = Test of ccEmailField
        messages {
            success = TEXT
            success {
                value = <p>See you</p>
            }
        }
    }
}
