    I’m getting an error message in all contact forms, saying “Invalid mailbox syntax is used”. The error appears in the Additional Headers, even though what I have there is exactly as it’s supposed to be (per this page: https://contactform7.com/adding-cc-bcc-and-other-mail-headers/). This is the setup I have:
    Cc: [email protected]
    Reply-To: [E-mail]

    Is this a false error or am I doing something wrong? It never used to be a problem before.

    The page I need help with: [log in to see the link]
