Sorry. Missed that part in install doc. Maybe other html_mail configuration options have configuration defaults and work without config.php, but spellcheck depends variable which is only set in configuration file. Your error indicates that html_mail_aspell_path configuration setting is not set.
Please create plugin configuration file.
