By default CustomFieldValuesAsString separates values with newlines.
Newlines in email header values are invalid unless they are followed by
a space to indicate a value continuation. This is basic rfc822 compliance.

Try this:

   Subject: { $Ticket->CustomFieldValuesAsString('CF Name', Separator => ", ") }

That is, using an alternate separator than a newline.
