I’m also getting a “This field has syntax errors.” Error when the only thing I have in Additional Headers is this:
Reply-To: [email]
Make sure that in the FORM the email field is a required (*) field:
[email* email]
If the client doesn’t want that to be mandatory however?
Will the form still work?
It was the mandatory email field that was missing.
I set-up a text field instead of email.
Thank you!

Great to hear that solved things.

You can disable the configuration validator by adding:
define( 'WPCF7_VALIDATE_CONFIGURATION', false );
to your wp-config.php, or:
add_filter( 'wpcf7_validate_configuration', '__return_false' );
to your theme’s functions.php. Then test the form and see how it behaves on reply both with and without the email field being populated by the sender,
