 * 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.
