Additional Headers [your-email2]

Hi all,

long time I work on Additional Headers with cc: [your-email2] on second email. It works every time with the filed [your-email2] from getting in form. Now I get a note that “Invalid mailbox syntax is used”.

The filed in form is [email your-email2] so it’s markt every time as email.

Any idea what problem it is? Thanks in advance.
