When digest program should run ? Anytime OK. Please edit crontab. Can we change default compression style in digest delivery ? No since &fml8; supports only MIME/Multipart now. Can we specify parameters in running "makefml add" ? No since &fml8; supports only MIME/Multipart now. Can we log digest log mesages in the file other than the default log file ? Not configurable. But you can if you us HOOK. [Example] $article_digest_prepare_start_hook = q{ $config->{ log_file } = "/some/where/log.digest"; };
